We demonstrate time-bin entanglement generation in telecom wavelength using a 7 μm
radius Si micro-ring resonator pumped by a continuous wave laser. The resonator structure
can enhance spontaneous four wave mixing, leading to a photon pair generation rate of
about 90-100 Hz with a laser pump power of as low as− 3.92 dBm (0.41 mW). We succeed
in observing time-bin entanglement with the visibility over 92%. Moreover, wavelength-
tunability of the entangled photon pair is demonstrated by changing the operation …
