Introduction

Boris G Kharas is a notable inventor based in Needham, MA (US). He has made significant contributions to the field of optical engineering and photonic integrated circuits. With a total of 4 patents, Kharas has developed innovative technologies that enhance optical beam steering and integration of light sources on chips.

Latest Patents

One of Kharas's latest patents is the "Planar Luneburg lens system for two-dimensional optical beam steering." This integrated optical beam steering device features a planar Luneburg lens that collimates beams from various inputs in different directions within the lens plane. It includes a curved grating coupler that diffracts the collimated beams out of the lens plane. This device can operate over an extensive field of view—up to 180°—without aberrations off boresight, ensuring uniform beam quality in all directions. The lens is robust against misalignment and fabrication imperfections, and it can be manufactured using standard CMOS processes.

Another significant patent is for "Hybrid integration for photonic integrated circuits." This technology allows for the manipulation of light on a chip for telecommunications and information processing. Kharas's approach improves hybrid integration by forming a recess in the photonic integrated circuit (PIC) to accommodate a III-V or II-VI photonic chip. This method enables precise vertical and lateral alignment during the flip-chip bonding process.
