T-014053

— A non-reciprocal transmission device based on PT symmetry was previously theorized but never before constructed and shown to work at useful optical wavelengths. The new structure allows creation of the miniaturized optical isolation function without use of the century+ known Faraday effect. Optica…

— WGM microresonators are an immature technology with room for improvement Microresonators are optical devices that are an important component of microlasers used in optoelectronics, data communications, and sensing. Most microresonators are WGM type, which confine light to a very small volume for si…
