Title: The Innovations of Sung-Nee George Chu
Introduction
Sung-Nee George Chu is a prominent inventor based in Murray Hill, NJ (US). He has made significant contributions to the field of optoelectronics, holding a total of 12 patents. His work focuses on enhancing the performance and reliability of semiconductor lasers and optoelectronic devices.
Latest Patents
One of his latest patents is titled "Aging in tunable semiconductor lasers." This process evaluates the aging properties of a distributed Bragg reflector (DBR) laser. The method involves illuminating a Bragg grating of the DBR laser with light while the laser is supplied with a tuning current and is not lasing. Additionally, it includes performing an action on the DBR laser based on the wavelength of a Bragg peak in the reflected light and the value of the tuning current supplied during the illumination.
Another notable patent is "Dopant diffusion blocking for optoelectronic devices using InAlAs and/or InGaAlAs." This method aims to decrease the diffusion of dopant atoms in the active region of optoelectronic devices. It employs multiple layers of InAlAs and/or InGaAlAs to prevent direct contact between the dopant atoms and the active region, as well as among adjacent doped regions. The invention also discloses a semi-insulating buried ridge structure that suppresses the interdiffusion of different types of dopant atoms.
