Deep purple technology has been committed to the technical development of UVC chips for a long time. Recently, the company's R & D team has made continuous exploration in epitaxy and chip technology, and successfully achieved a breakthrough in UVC high-power chip technology. Through the optimization of epitaxial bottom layer, the design of core layer structure, the design of new p-type transparent electrode and special reflective electrode, a high-power chip with a single optical output power of more than 140MW has been successfully developed.

At present, this product has passed several rounds of verification by several customers and entered the stage of batch supply. The single core size of deep purple technology is 45*45mil. At present, the chip has been tested for several rounds of reliability.
