Title: Nelson Vachon: An Innovator in Fiber Optics

Introduction

Nelson Vachon, an accomplished inventor based in Mascouche, Canada, has made significant contributions to the field of fiber optics. With a total of two patents to his name, Vachon has developed innovative solutions that enhance the functionality of optical systems.

Latest Patents

Vachon's most recent patents showcase his expertise in creating advanced optical devices. One of his notable inventions is the "Multimode Fiber Outer Cladding Coupler for Multi-Clad Fibers." This device features a structure in which multiple tapered pump fibers are laterally coupled to a multi-clad fiber, such as a double clad fiber (DCF). The coupler is constructed by forming a fiber bundle with tapered pump fibers positioned around the multi-clad fiber, which are then twisted and fused to converge towards a waist. Additionally, at this waist, the structure can be cleaved and spliced with a like multi-clad fiber.

His second patent, the "Optical Phase Shifting, Splitting and Combining Device," details a Mach-Zehnder device that includes a couple of achromatic coupling regions linked to input and output ports. This device features an intermediate region with distinct branches, one of which defines a phase-shifting portion that creates a polarization selective phase shift. This innovation allows the device to serve as either a coupler or splitter while remaining generally wavelength insensitive.
