OXFORD, Mass., Aug. 26, 2013 — Armen Dallakian, a former consultant to IPG Photonics Corp., claims that he is the inventor of a simple, highly effective technique to align light beams as they pass from one fiber optic cable to another at a coupler or switch, and that the technology was misappropriated by IPG. Dallakian is demanding a jury trial in his civil complaint, filed Aug. 5 against IPG in the US District Court for the District of Massachusetts.

    coupler
    1. In color development, the chemical that combines with certain by-products of the development procedure to form a dye. 2. Device for distributing optical power among two or more ports. 3. Device for coupling optical power between a waveguide and a source or detector, and thus sometimes interchangeable with a connector.
    optical component
    One or more optical elements – typically cemented together - in an optical system that are treated as a single group; e.g., a beamsplitter, or a cemented doublet or triplet.
