Title: Mark E Kuznetsov: Innovator in Optical Devices

Introduction

Mark E Kuznetsov is a notable inventor based in East Brunswick, NJ (US). He has made significant contributions to the field of optical devices, holding a total of 2 patents. His work primarily focuses on tunable filters and optical filters, showcasing his expertise in advanced optical technologies.

Latest Patents

Kuznetsov's latest patents include the "Asymmetric Y-branch optical device" and "Optical filter having multiple interferometric stages." The Asymmetric Y-branch optical device relates to a new tunable filter that, when used as an intracavity mode selecting filter in a semiconductor laser structure, provides a large tuning range. This invention features a two-branch asymmetric Y-branch tunable filter, where the ends of the two branches terminate at a common plane. In another embodiment, the invention utilizes a cascade of two or more Y-branches to place several asymmetrical Y-branch filters in parallel. The second patent, the Optical filter having multiple interferometric stages, describes an interferometric, channel-dropping optical filter that includes a pair of planar waveguides. These waveguides are spaced apart by a periodically varied distance along the longitudinal axis of the filter to effect a periodic optical coupling between them. The design includes at least three coupling locations, each associated with a coupling constant, with the coupling constants decreasing symmetrically from the center of the filter toward the ends.
