Introduction

Xiaolong Fang is a notable inventor based in Fremont, California. He has made significant contributions to the field of optoelectronics, holding three patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is the "Self-mixing interference device with tunable microelectromechanical system." This invention involves self-mixing interferometry (SMI) sensors that may include vertical cavity surface emitting lasers (VCSEL), photodetectors, and microelectromechanical systems (MEMS). The VCSEL, photodetectors, and MEMS may be vertically stacked, with the MEMS being moveable relative to the VCSEL. This movement can change the cavity length associated with the VCSEL, thereby altering certain properties of the emitted light, such as its wavelength value. Another significant patent is the "VCSEL array with tight pitch and high efficiency." This optoelectronic device features a semiconductor substrate with multiple sets of thin-film layers that define a lower distributed Bragg-reflector (DBR) stack and an optical emission region. Electrodes are strategically placed around the mesa to apply an excitation current to the optical emission region.
