Title: Joseph Vanniasinkam: Innovator in Optical Technologies

Introduction

Joseph Vanniasinkam is a notable inventor based in San Ramon, CA (US), recognized for his contributions to optical technologies. He holds a total of six patents, showcasing his innovative spirit and technical expertise in the field.

Latest Patents

Among his latest inventions is the "Optical Multiplexer and Transmitter." This apparatus is designed for multiplexing multiple light waves with different wavelengths. It comprises a laser sub-assembly, a multiplexer sub-assembly, and a receptacle sub-assembly. The laser sub-assembly features several lasers that emit light waves of varying wavelengths. These light waves are then multiplexed in the multiplexer sub-assembly and subsequently coupled to an optical fiber via the receptacle sub-assembly.

Another significant patent is the "Optical ROSA for Long Reach Optical Transceiver." This invention presents a receiver optical amplifier assembly (ROSA) that enhances alignment tolerances. The ROSA includes a multimode fiber stub that receives a light beam from a single-mode optical fiber. A lens system focuses the light beam from the multimode fiber stub onto the active area of an optical detector chip. The multimode fiber stub functions as a GRIN lens, optimizing the spot size on the active area. Additionally, the design can improve return loss characteristics by incorporating an angled surface on the multimode fiber stub and adjusting the active area of the optical detector chip off-axis.
