Title: **Innovations of Arnab Sarkar: A Pioneer in Optical Fiber Technology**
Introduction
Arnab Sarkar, an accomplished inventor based in Big Flats, NY, is renowned for his contributions to the field of optical fiber technology. With a remarkable portfolio of seven patents, Sarkar's innovations stand at the forefront of advancements in optical communication.
Latest Patents
Among his notable patents is a method of forming an optical fiber with a laminated core. This groundbreaking process involves manufacturing a preform that consists of layers of different glass compositions. In a unique embodiment of his invention, Sarkar modifies the conventional Chemical Vapor Deposition (CVD) process by temporarily halting the rotation of the substrate tube. The tube is asymmetrically heated, causing a vapor mixture flowing through to react only at the area being heated, resulting in a longitudinal strip of glass particles. The rotation resumes, and the tube is heated to fuse the glass particles, ultimately forming a stable glassy material.
Another significant patent by Sarkar is focused on creating a polarization-retaining single-mode optical waveguide. This invention carefully fabricates a single-mode optical waveguide that experiences stress-induced birefringence, ensuring optimal performance. The process begins by forming a hollow intermediate product through the deposition of layers of cladding and core glass on a substrate tube. Heating opposite sides of this intermediate product compacts it into a solid preform with an oblong cross-section. Subsequently, a layer of flame hydrolysis-produced soot is added, forming a dense glass cladding layer that contributes to the unique properties of the final fiber.
