    We experimentally demonstrate quantum channel monitoring by wavelength-time multiplexing of classical wrapper bits with quantum payloads. Bit-error-rate measurements of 5 Gb/s classical bits infer the coincidence-to-accidental ratio of the quantum channel up to 13.3 dB.

    We study spontaneous four-wave mixing and spontaneous Raman scattering (SpRS) in a CMOS microring cavity in the C-band and find that the latter contributes a significant fraction to the signal/idler photon flux. We expect operation in the O-band to be less affected by SpRS due to higher confinement of the O-band light in crystalline Si in this device.
