Efficient fiber coupling of telecom single-photons from circular Bragg gratings
A 3D-printed lens on a fiber tip and a bare cleaved fiber both couple telecom-wavelength single photons from circular Bragg gratings with up to 3.0±0.2 times higher end-to-end count rate than a microscope objective setup.
