A method of achieving integrated microspectrometer with small size, high-energy efficiency, and high spectrum resolution is proposed. This spectrometer utilizes the single-pixilated liquid crystal (LC) and a matched sparse representation algorithm. The properties of compact size and high-energy efficiency are benefit to the configuration of single-pixilated LC which forms a filter array in the time...
Materials that undergo an electronic phase change in a reversible manner open up new directions for research in light–matter interactions and photonic devices. The highly tunable dielectric properties, along with the spatial control of insulating and metallic domains, create photonic-crystal-like environments to control light propagation. In this brief overview, recent advances in photonics that utilize...
