OPTOELECTRONIC NEURAL NETWORKS

Optoelectronic neural networks comprise a system of interconnected processing units (neurons) interconnected by integrated photonic waveguides. The processing units receive photonic signals from other units. Each unit sums the received signals on a waveguide-integrated photon detector, and when the...

Phase Modulation Noise Reducer

The phase modulation (PM) noise reducer is a novel scheme for lowering the PM noise of an oscillator. Low PM noise, or phase instability, is among the most important metrics for oscillators used in modern civilian and military applications. One can sense and correct an oscillator’s PM noise by...
