Introduction

Robert M. Lien is a notable inventor based in Chester, NJ, with a focus on optical technologies. He holds two patents that showcase his expertise in the field of optical couplers and connectors. His work has contributed significantly to advancements in optical fiber technology.

Latest Patents

One of Lien's latest patents is the "Molded polymeric resin-filled optical coupler." This invention comprises two low-refractive index plastic molded subassemblies. One subassembly features an optically finished mixing region with a channel that has a V-shaped lower portion. The mixing region subassembly is covered with a lid subassembly made from the same material. During assembly, optical fibers are inserted into the mixing region, which is then filled with a high index material to create a high-refractive index waveguide core region in the channel. The molded low-refractive index subassemblies provide a waveguide cladding around the high-refractive index waveguide core. This design achieves low costs by utilizing optically finished metal molds, eliminating the need for polishing each subassembly.

Another significant patent is the "Optical fiber connector." This invention includes a fiber optical end connector featuring a grooved base member with a grooved silicon block mounted on it. The design incorporates means for holding optical fibers in the grooves on both the base member and the silicon block, enhancing the efficiency of optical connections.
