MIT researchers discovered a paradoxical phenomenon in optical physics that could enable a new bioimaging method that's ...

Abstract: We present an external cavity laser formed by coupling a III-V gain chip to a silicon nitride chip using an alignment tolerant multimode edge coupler, resulting in a misalignment tolerance ...

Abstract: Light amplification by stimulated emission of radiation (laser) sources has many advantages for use in high-data-rate optical wireless communications (OWCs). In particular, the low-cost and ...

An international team of physicists has achieved a significant advance in laser science, demonstrating for the first time a ...
