The optical properties of photonic crystals are closely related to their lattice constants, which are usually required to be in the same order of magnitude as the operating wavelength. In a crystal material, the photonic crystal structure is formed by the periodic arrangement in space of units whose dielectric constant is different from that of the crystal itself, and whose lattice constant depend...
Recently, US military industry giant Lockheed Martin announced that it will significantly increase its additive manufacturing capabilities and expand its factory in Texas. The expansion project includes approximately 16000 square feet of dedicated space for 3D printing technology, and the addition of some of the largest large format multi laser printers in the space (it is worth noting that Lockhe...
Improvements in LiDAR technology will assist NASA scientists and explorers in remote sensing and measurement, surveying, 3D image scanning, hazard detection and avoidance, and navigation.Like sonar that uses light instead of sound, LiDAR technology is increasingly helping NASA scientists and explorers with remote sensing and measurement, surveying, 3D image scanning, hazard detection and avoidance...
Zhao Yun/Columbia Engineering Company provided an advanced schematic of a photonic integrated chip, which aims to convert high-frequency signals into low-frequency signals using all optical frequency division.Scientists have built a small all optical device with the lowest microwave noise ever recorded on integrated chips.In order to improve the performance of electronic devices used for global n...
Chip manufacturer GlobalFoundries (GF) has partnered with fiber optic giant Corning to provide co packaged optical (CPO) interconnects for artificial intelligence data centers.The firms say that Corning’s “GlassBridge” technology, a glass-waveguide based edge-coupler compatible with the v-grooves used in GF’s silicon photonics platform, is wanted for high-bandwidth, power-efficient optical links.“...
