We propose a method for the programmable generation of time-frequency mode (TFM) encoded quantum states of light on the silicon-on-insulator (SOI) platform. The state generator consists of an N-tap finite impulse response filter and a Mach-Zehnder interferometer (MZI)-based coupled-ring resonator. Through numerical simulations, its capability of producing TFM-encoded maximally entangled states in two, three, and four dimensions is theoretically demonstrated, with fidelities of 0.950, 0.954, and 0.971, respectively.
