Title: Steve Yiqiang Li: Innovator in Semiconductor Laser Technology
Introduction
Steve Yiqiang Li is a prominent inventor based in San Jose, California. He has made significant contributions to the field of semiconductor laser technology. With a total of 2 patents to his name, his work focuses on enhancing the capabilities of semiconductor lasers.
Latest Patents
One of Steve's latest patents is for a semiconductor external cavity laser with integrated planar waveguide Bragg grating and wide-bandwidth frequency modulation. This innovative laser design is packaged in a standard form-factor package, such as a 14-pin butterfly package. The front end of the cavity features an integrated planar circuit, specifically a silica-on-silicon planar lightwave circuit with Bragg gratings. The back facet of the laser is designed with a high-reflection (HR) coated LiNbO phase tuning section in a double pass configuration. An AC-voltage signal applied to the electrodes of the phase tuning section modulates the refractive index of the propagating TE-polarization mode of the external cavity, resulting in frequency modulation. This frequency modulation is notable for not being associated with any thermal behavior of the gain element included in the external cavity laser, and it exhibits a negligible phase delay over a wide bandwidth.
