The pith

A three-core fiber Fabry-Perot resonator generates two mutually coherent frequency combs with a 112 kHz repetition rate offset.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper shows how a compact resonator made from three-core optical fiber can produce two cavity-soliton frequency combs that stay phase-locked to the same driving laser. A fan-in/fan-out coupler multiplexes the light so the entire experiment stays in fiber. The cores have slightly different group indices, which creates a 112 kHz difference in the 1.27 GHz repetition rates; this offset lets the pair perform dual-comb spectroscopy on a narrow absorption feature. The result is a simple, integrable source of dual combs without free-space optics or separate cavities.

Core claim

The central claim is that a Fabry-Perot resonator fabricated in three-core fiber generates two mutually coherent cavity-soliton combs locked to a single driving laser; the combs have 1.27 GHz repetition rates and more than 40 nm bandwidth, with a 112 kHz offset arising from the cores' group-index mismatch, and this offset enables a fully fiber-based dual-comb spectroscopy measurement of a 0.1 nm absorption band.

What carries the argument

The three-core fiber Fabry-Perot resonator, in which independent soliton formation in each core combined with a small group-index difference produces the repetition-rate offset between the two combs.

If this is right

  • The entire dual-comb apparatus can be realized with only fiber components and standard connectors.
  • Cavity solitons form independently in each core yet share the same pump laser, preserving mutual coherence.
  • The 112 kHz offset is large enough for dual-comb spectroscopy yet small enough to keep both combs within a common detection bandwidth.
  • A proof-of-concept absorption measurement resolves a 0.1 nm spectral feature with the fiber dual-comb pair.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • Adding more cores to the same fiber type could generate three or more simultaneous combs with distinct offsets.
  • The design may allow monolithic integration of the resonator with fiber amplifiers or modulators for portable dual-comb instruments.
  • Long-term drift measurements of the 112 kHz offset would test whether the core-to-core index difference remains constant enough for metrology applications.

Load-bearing premise

The three cores must remain optically independent with a stable group-index difference and the fan-in/fan-out system must add negligible crosstalk or instability that would destroy coherence or erase the 112 kHz offset.

What would settle it

If the two output combs show no mutual coherence or if their repetition-rate difference is absent or drifts far from 112 kHz under locked operation, the claim that the three-core resonator stably produces dual combs would be falsified.

read the original abstract

Fiber Fabry-Perot resonators have proven their ability to generate broad and stable optical frequency combs, and are ideal devices for fiber systems as they are high-Q, compact, and easily integrated with FC/PC connectors. Here, we present an advanced fiber Fabry-Perot resonator designed for multi-frequency comb generation and spatial multiplexing. The resonator is fabricated using a three-core optical fiber and is able to generate two mutually coherent frequency combs while being locked to a driving laser. Multiplexing of the combs is achieved with a fan-in/fan-out system, enabling a fully fiber-based experimental setup. The generated combs, induced by cavity solitons, feature a 1.27 GHz repetition rate and a bandwidth above 40 nm. A slight difference in the group index of each core leads to a 112 kHz repetition rate offset between the combs, enabling dual-comb spectroscopy proof-of-concept measurement of a 0.1 nm absorption band.

Referee Report

2 major / 2 minor

Summary. The manuscript presents a three-core fiber Fabry-Perot resonator fabricated for dual-frequency comb generation. It reports two mutually coherent cavity-soliton combs with 1.27 GHz repetition rate and >40 nm bandwidth, locked to a driving laser via a fan-in/fan-out multiplexing system. A 112 kHz repetition-rate offset arising from core-to-core group-index differences enables a proof-of-concept dual-comb spectroscopy measurement of a 0.1 nm absorption band.

Significance. If the reported coherence and offset stability hold, the work offers a compact, fiber-integrated route to dual-comb sources that avoids separate resonators and could scale to multi-comb systems. The spatial-multiplexing approach using multi-core fiber is a practical advance for applications in spectroscopy and metrology.

major comments (2)
  1. [Experimental results and discussion] The central claim of mutually coherent combs with a stable 112 kHz offset requires that evanescent coupling between cores remains negligible over the resonator length and that the fan-in/fan-out introduces neither differential loss nor excess phase noise. No quantitative bound on crosstalk, coupling coefficient, or beat-note visibility is supplied to support this assumption, which is load-bearing for the dual-comb functionality and the observed offset.
  2. [Results] The proof-of-concept dual-comb spectroscopy measurement of the 0.1 nm absorption band is presented without accompanying data on signal-to-noise ratio, integration time, or long-term stability of the 112 kHz offset. This makes it impossible to assess whether the mutual coherence is sufficient for practical spectroscopy.
minor comments (2)
  1. [Abstract and Results] The bandwidth is stated only as 'above 40 nm'; please report the exact 3 dB or 10 dB bandwidth, center wavelength, and include the corresponding optical spectrum figure with scale.
  2. [Results] Add uncertainty estimates or error bars for the reported 1.27 GHz repetition rate and 112 kHz offset, and clarify how the group-index difference was measured or calculated.

  1. Referee: [Experimental results and discussion] The central claim of mutually coherent combs with a stable 112 kHz offset requires that evanescent coupling between cores remains negligible over the resonator length and that the fan-in/fan-out introduces neither differential loss nor excess phase noise. No quantitative bound on crosstalk, coupling coefficient, or beat-note visibility is supplied to support this assumption, which is load-bearing for the dual-comb functionality and the observed offset.

    Authors: We agree that explicit quantitative support for negligible inter-core coupling would strengthen the central claim. The three-core fiber geometry is chosen with sufficient core separation to suppress evanescent coupling over the resonator length, and the fan-in/fan-out is a standard low-crosstalk device. To address the referee's point, the revised manuscript will include a brief calculation of the expected coupling coefficient based on the fiber mode-field diameter and core pitch, together with any measured beat-note visibility data available from our coherence characterization. These additions will be placed in the results section. revision: yes

  2. Referee: [Results] The proof-of-concept dual-comb spectroscopy measurement of the 0.1 nm absorption band is presented without accompanying data on signal-to-noise ratio, integration time, or long-term stability of the 112 kHz offset. This makes it impossible to assess whether the mutual coherence is sufficient for practical spectroscopy.

    Authors: The spectroscopy result is presented strictly as a proof-of-concept to illustrate the utility of the 112 kHz offset. We will revise the manuscript to report the integration time used for the displayed trace and to extract an SNR estimate directly from the depth and noise floor of the observed absorption feature. Short-term stability of the offset is visible in the beat-note data already shown; however, dedicated long-term stability measurements were not performed in this work. revision: partial

standing simulated objections not resolved
  • Quantitative long-term stability data for the 112 kHz repetition-rate offset over timescales longer than those captured in the existing measurements.

Circularity Check

0 steps flagged

No circularity: experimental measurements of dual-comb generation are direct observations, not derived quantities.

full rationale

The manuscript is an experimental report on fabricating and characterizing a three-core fiber Fabry-Perot resonator. Reported values (1.27 GHz repetition rate, >40 nm bandwidth, 112 kHz offset) are measured outcomes from cavity solitons and group-index differences, with no equations, fitted parameters, or first-principles derivations presented that could reduce to the inputs by construction. No self-citations, ansatzes, or uniqueness theorems are invoked as load-bearing steps in any derivation chain. The central claims rest on empirical setup performance and spectral measurements, which remain independently falsifiable.
