Title: Sze-Keung Kwong: Innovator in Laser Technology
Introduction
Sze-Keung Kwong is a notable inventor based in Long Beach, California, recognized for his contributions to laser technology. He holds a total of five patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
One of his latest patents is a laser module with compliant optical fiber coupling. This small module is designed to convert an electrical signal into a modulated light signal on an optical fiber. It comprises a housing, a laser mounted on a laser substrate within the housing, a GRIN lens, and an optical isolator downstream from the laser. A precision capillary holds the optical fiber downstream from the optical isolator. The arrangement of the laser, lens, optical isolator, and fiber is optimized to maximize light output through the fiber. The optical fiber is sealed to the housing at one point and is free to move axially in the capillary, minimizing mechanical stress on the fiber.
Another significant patent is for a superluminescent diode and single mode laser. This invention features a buried heterostructure window device with an elongated layer of gain medium surrounded by a lower index of refraction medium, guiding light along the length of the gain medium. An antireflective layer is deposited on the output end of the gain layer to minimize reflections. The device can produce strong superluminescent output when pumped with moderate power levels. When pumped above the lasing threshold, it generates a single mode laser with side band power significantly lower than the principal oscillation mode.
