Nonlinear pluggable optics: Digital signal processing-free Intensity Modulated Direct Detection links using analog photonic Next Generation Reservoir Computing

In this work, we propose a Nonlinear Pluggable Optic (NLPO) transceiver that combines the low latency and low power consumption of Linear Pluggable Optics (LPO) with the range and robustness of digital signal processing (DSP)-based transceivers. The proposed NLPO uses an analog p...

Efficient Generation of Entangled Photons in the Telecommunications Range Using Nonlinear Metasurfaces Integrated With ScAlN/GaN Heterostructures

ABSTRACT Entangled photons provide non‐classical correlations that enable measurement sensitivities beyond classical limits, scalable fault‐tolerant quantum computation, and fundamentally secure quantum communication, making them a foundational necessity for next‐generation quant...

ReDON: Recurrent Diffractive Optical Neural Processor with Reconfigurable Self-Modulated Nonlinearity

Diffractive optical neural networks (DONNs) have demonstrated unparalleled energy efficiency and parallelism by processing information directly in the optical domain. However, their computational expressivity is constrained by static, passive diffractive phase masks that lack eff...
