Title: Innovations by Gang Yun
Introduction
Gang Yun is a notable inventor based in Vanier, Canada. He has made significant contributions to the field of optical interconnection devices and photodiode technology. With a total of 2 patents, his work has implications for telecommunications and computer equipment.
Latest Patents
One of his latest patents is an optical interconnection device that utilizes N.times.N optical couplers. These couplers are essential in local area networks and backplanes of telecommunications and computer equipment. They employ BRAGG volume diffraction means to couple light beams between inputs and outputs. Notably, the number of gratings is reduced through a method known as 'grating degeneration', allowing one grating to be shared by at least two wave pairs simultaneously. The arrangement of light wave directions in the dielectric slab or the lateral positions of fiber ends is crucial for achieving this reduction. Additionally, a reduced number of gratings can be accomplished using a 'sandwiched' structure with multi-layered dielectric slabs, and both embodiments can be combined in a single coupler.
Another significant patent by Gang Yun is an optical taper designed to increase the effective area of a photodiode. This optical receiver features a photodiode with a surface area suitable for receiving signals at high bit rates. The optical taper consists of a head and a tail, where the head has a greater diameter than the tail and is co-axial with it. The tail aligns with the photodiode, enhancing its performance.
