— 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…
— Technology Description
A team of engineers in Prof. Lan Yang’s laboratory have developed ultra-sensitive, broad bandwidth optical sensors that could detect sound in low-cost, discrete hearing devices. This technology utilizes whispering gallery mode (WGM) resonators as compact photonic vibra…
— 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…
