We report a compact 1×8 silicon Mux/DeMux with ring tuning efficiency of <3µW/GHz using back-side substrate removal technique. Total power of <4.1mW was measured to tune the device to a 1.6nm wavelength grid.
We report an ultra-low power 100Gbps silicon photonic WDM transmitter tunable with off-chip laser sources. The hybrid CMOS transmitter consists of eight 12.6Gbps WDM channels and consumes a total on-chip power of 33mW.
We report a high-contrast 40Gb/s ring modulator with integrated thermal tuning fabricated in a 130nm CMOS process. Under 2V modulation, its optical eyes showed extinction ratios of 7dB at 40Gb/s and 2.3dB at 44Gb/s.
We report a 25Gb/s ring modulator with integrated thermal tuning fabricated in a 130nm CMOS process. With 2Vpp modulation, the optical eye shows >6dB extinction ratio. Modulation energy is estimated <24fJ/bit from circuit modeling.
We present add-drop filters manufactured as ring resonators in commercial 130 nm SOI CMOS technology with thermal tuning. Their thermal impedance has been dramatically increased by the selective removal of the substrate resulting in a 20,12× increase in tuning efficiency for 100, 30 micron radius device.
We present a high speed silicon micro-ring modulator with a tunable resonant wavelength enabled by a local heater. With a ~46 mW thermal tuning power, the working wavelength can expend to more than 100 nm.
