We present a silicon photonic architecture for accelerating collective commu nications in distributed deep learning. We demonstrate a 22% job completion time improvement in a small-scale testbed and 1.4 to 5.9x improvement in large-scale simulations.

We demonstrate the thermal control of cascaded micro-ring DWDM filters using a single photodiode. The streamlined implementation maintains stable operation of the 8-ring bus with less than 0.1dB BER power penalty on an 8x10Gb/s link.

We present the first experimental demonstration of a 25 Gbps optical PAM4 signal transmission through a microring-based Clos topology under realistic operating conditions. We observe a 1.1-dBm power penalty at the bit error rate of 1.03 × 10−7.

A detailed analysis of fundamental tradeoffs between ring radius and coupling gap size is presented to draw realistic borders of the possible design space for microring resonators (MRRs). The coupling coefficient for the ring-waveguide structure is e

We demonstrate an optical equalization for mitigating pulsewidth distortion using a MRR-based SiP switch. This approach is robust to different level of pulsewidth distortion. A 4.5-dB-enhanced detection sensitivity is obtained at a 12.5-Gbits/s data

We demonstrate an optimized silicon photonic link architecture using components from the AIM PDK that achieves an ultra-low sub-pJ/bit power consumption with an aggregate bandwidth of 480 Gb/s. At the transmitter, micro-disk modulators are cascaded a
