Glass provides high dimensional stability and flatness, enabling high-throughput electronic assembly with precision optical alignment for co-packaged optics (CPO) applications. Optical waveguides can be integrated in the glass core material by thermal silver ion-exchange (IOX) process at temperatures around 350°C fiber to chip connectivity. Currently available IOX glasses degrade due ion mobility operating conditions so we designed a new composition stable over lifetime of five years an...
The unique properties of two-dimensional materials for light emission, detection, and modulation make them ideal integrated photonic devices. However, identifying if the films are indeed monolayers is a time-consuming process even well-trained operators. We develop an intelligent algorithm to detect WSe 2 , MoS h-BN autonomously using Digital Image Processing Deep Learning with high accuracy rate, avoiding human interaction any additional characterization tests. demonstrate autonomous...
A fast and automated scheme for general polarization transformations holds great value in adaptive optics, quantum information, virtually all applications involving light-matter light-light interactions. We present an experiment that uses a liquid crystal on silicon spatial light modulator to perform field. experimentally demonstrate the point-by-point conversion of uniformly polarized fields across wavefront realize arbitrary, spatially varying states. Additionally, we field with arbitrary...
Light sources or lasers based on two-dimensional (2D) materials have been recently demonstrated with different photonic cavities emitting into free space.

With the ever-increasing need for higher data rates, datacom and telecom industries are now migrating to silicon photonics achieve rates with reduced manufacturing costs. However, optical packaging of integrated photonic devices multiple I/O ports remains a slow expensive process.
