WebMar 17, 2024 · Photonic-crystal lasers with two-dimensionally arranged gain and loss sections for high-peak-power short-pulse operation By using engineered gain and loss sections in a photonic crystal laser,... WebSep 3, 2004 · The fabricated single-cell photonic crystal cavities are electrically pulse-pumped at room temperature. The width and the period of the injected electrical current pulse are ∼6 ns and 2.5 μs, respectively ( 18 ). The emitted photons are collected by a 50× microscope objective lens with a numerical aperture of 0.42 and fed to a spectrometer.
Electrically Driven Single-Cell Photonic Crystal Laser Science
Photonics is a branch of optics that involves the application of generation, detection, and manipulation of light in form of photons through emission, transmission, modulation, signal processing, switching, amplification, and sensing. Though covering all light's technical applications over the whole spectrum, most photonic applications are in the range of visible and near-inf… WebPhotonics Media Editors. Photonics is the study of light and other types of radiant energy whose quantum unit is the photon.
