Self-organizing photorefractive frequency demultiplexer [PDF]
Optics Letters, 1991 We demonstrate a self-organizing photorefractive circuit that demultiplexes a beam that has two signals imposed on separate optical carrier frequencies into two beams, each containing one of the signals on its carrier. Unlike conventional demultiplexing techniques, this method requires little a priori knowledge about the carrier frequencies. The signal

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Mode Suppression in Injection Locked Multi-Mode and Single-Mode Lasers for Optical Demultiplexing
Photonics, 2019 Optical injection locking has been demonstrated as an effective filter for optical communications. These optical filters have advantages over conventional passive filters, as they can be used on active material, allowing them to be monolithically ...

Universal quantum computation with the Orbital Angular Momentum of a single photon
, 2010 We prove that a single photon with quantum data encoded in its orbital angular momentum can be manipulated with simple optical elements to provide any desired quantum computation. We will show how to build any quantum unitary operator using beamsplitters,

Slow light enabled wavelength demultiplexing [PDF]
2016 18th International Conference on Transparent Optical Networks (ICTON), 2016 Photonic crystal waveguides supporting band gap guided modes hold great potential to tailor the group velocity of propagating light. We propose and explore different wavelength demultiplexer design approaches that utilize slow light concept. By altering the dielectric filling factors of each waveguide segment, one can show that different

Inverse Design for Robust Inference in Integrated Computational Spectrometry
Nanophotonics, Volume 15, Issue 7, 13 April 2026.This work demonstrates that integrated computational spectrometers can be inverse‐designed to substantially improve noise tolerance without relying on training data or specific inference algorithms, offering an alternative to conventional end‐to‐end co‐design strategies.
