We report an all-silicon co-design based integrated low noise and wideband photoreceiver frontend system for noise-sensitive receivers. We also demonstrate a defect mediated silicon APD with 8 GHz small-signal bandwidth and a high-gain CMOS transimpedance amplifier with an input SNR of 15 dB.

An optical half-adder of two 4-PSK channels using nonlinear wave mixing is demonstrated. The two phase-encoded 5-Gbaud outputs (i.e., Carry and Sum) are generated with optical signal-to-noise ratio penalties of <5dB at the BER of 3.8e-3.

We develop a quantum network simulation framework designed for integration into tactical simulation tools. It extends the quantum networking tool SQUANCH with realistic fiber and free-space channel models and implements subroutines for simulating entanglement-based QKD. We benchmark our framework using a published free-space QKD experiment.

We designed a compact integrated Silicon Nitride 1 x 3 balanced optical power splitter using density-based topology optimization with built-in fabrication constraints. We experimentally validate our design on a commercial foundry process with a splitting ratio of 30-36-33 % and an insertion loss of 2.48 dB across two wafers.

We report a high-speed (GHz rate) and hardware-friendly Neuromorphic Photonic Spiking Neural Network (pSNN) architecture formed by up to >1000 spiking nodes and built with a single off-the-shelf telecom Vertical-Cavity Surface Emitting Laser (VCSEL). We demonstrate the successful application of the proposed pSNN architecture to a complex nonlinear classification task, running at sub-nanosecond speeds per spike directly in the optical domain.
