Silicon 4×4 switch array based on carrier-injection for switching of multiple 40 Gbps WDM channels is reported. Operation in all 9 unique switch states and 12 possible I/O routings is verified with crosstalk less than 10 dB.
We report a low-power silicon photonic ring-resonator switch integrated with a CMOS driver that achieves sub 3.5-ns transition times, below -20-dB crosstalk, and ~1-mW combined switch and driver power consumption. Results are compared to non-resonant Mach-Zehnder based switches.
Error-free switching performance of a digital electro-optic silicon switch based on multi-stage Mach-Zehnder lattice is demonstrated. Robust crosstalk levels of lower than −15dB are obtained for drive-voltage noise levels exceeding 300mV while maintaining error-free operation.
A broadband, low-power optical switch is a key element for circuit-switched on-chip optical networks. We present a novel switch design based on a Mach-Zehnder lattice in SOI, featuring digital, broadband switching, low cross talk, and low insertion loss.
A compact multiwavelength laser source, which consists of four cascaded InP-microdisks coupled to one SOI waveguide, is introduced for WDM purposes. Equally distributed laser peaks and low crosstalk were obtained with the proposed structure.
