Title: Innovations by David L K Eng: A Look at His Patents in Fiber Optics

Introduction

David L K Eng, an inventive mind based in Fairfax Station, VA, has made significant contributions to the field of fiber optics through his patented technologies. With a total of two patents to his name, Eng has developed groundbreaking solutions that enhance the functionality of fiber optic switches.

Latest Patents

Eng's latest patents focus on tunable wavelength-selective fiber optic switches that utilize innovative mechanisms for controlling optical power. His first patent details a "Tunable wavelength-selective fiber optic switch employing moveable grating interaction with the evanescent field of a partially-cladding-removed fiber." This invention outlines a clever design where an optical fiber has part of its cladding removed to expose a window that allows access to the radially evanescent field. The switch features an adjustable positioning fixture that enables the fiber core, grating, and output waveguide to be repositioned to either a coupled or decoupled position, optimizing the switching process based on the wavelength of the optical power.

The second patent, "Fiber optic switch employing moveable structure interaction with the evanescent field of a cladding-removed fiber," presents a similar concept where the grating is moveably positioned within a window exposing the fiber core. This mechanism allows for interaction with the evanescent field when optical power is present, enhancing the performance of the fiber optic switch as it can switch between states to route specific wavelengths while leaving others unperturbed.
