Dual-Polarization Phase Retrieval Receiver in Silicon Photonics
Brian Stern, Hanzi Huang, Haoshuo Chen +2
We demonstrate a silicon photonic dual-polarization phase retrieval receiver. The receiver recovers phase from intensity-only measurements without a local oscillator or transmitted…
Record Photon Information Efficiency with Optical Clock Transmission and Recovery of 12.5 bits/photon over an Optical Channel with 77 dB Loss
René-Jean Essiambre, Cheng Guo, Sai Kanth Dacha +18
We experimentally demonstrate optical detection at 12.5~bits per incident photon, 9.4~dB higher than the theoretical limit of conventional coherent detection. A single laser transm…
Silicon Photonic Direct-Detection Phase Retrieval Receiver
Brian Stern, Haoshuo Chen, Kwangwoong Kim +3
We demonstrate a direct-detection phase retrieval receiver based on silicon photonics. The receiver implements strong dispersion and delay lines on a compact chip. We retrieve the…
Frequency Tunable Magnetostatic Wave Filters With Zero Static Power Magnetic Biasing Circuitry
Xingyu Du, Mohamad Hossein Idjadi, Yixiao Ding +7
A single tunable filter simplifies complexity, reduces insertion loss, and minimizes size compared to frequency switchable filter banks commonly used for radio frequency (RF) band…
Towards fully integrated photonic backpropagation training and inference using on-chip nonlinear activation and gradient functions
Farshid Ashtiani, Mohamad Hossein Idjadi
Gradient descent-based backpropagation training is widely used in many neural network systems. However, photonic implementation of such method is not straightforward mainly since h…
Modulation-free Laser Stabilization Technique Using Integrated Cavity-Coupled Mach-Zehnder Interferometer
Mohamad Hossein Idjadi, Kwangwoong Kim
Stable narrow-linewidth light sources play a significant role in many precision optical systems. Electro-optic laser frequency stabilization systems, such as the well-known Pound-D…
Enhanced Frequency Noise Discrimination Using Cavity-coupled Mach-Zehnder Interferometer
Mohamad Hossein Idjadi, Andrea Blanco-Redondo
Here, an enhanced frequency noise discriminator is proposed using a cavity-coupled Mach-Zehnder interferometer and demonstrated on a general-purpose programmable integrated photoni…
A surface-normal photodetector as nonlinear activation function in diffractive optical neural networks
Farshid Ashtiani, Mohamad Hossein Idjadi, Ting-Chen Hu +7
Optical neural networks (ONNs) enable high speed parallel and energy efficient processing compared to conventional digital electronic counterparts. However, realizing large scale s…
