Title: The Innovative Contributions of Sel B Colak
Introduction
Sel B Colak is a notable inventor based in Ossining, NY (US). He has made significant contributions to the field of optical waveguides, holding a total of 7 patents. His work focuses on advancing technologies that enhance the efficiency and functionality of optical devices.
Latest Patents
Colak's latest patents include groundbreaking inventions such as the "Actively Phased Matched Frequency Doubling Optical Waveguide." This invention describes a waveguide structure that is suitable for use as a frequency doubling device. The phase matching of the waveguide is controlled by the application of a control voltage. The waveguide consists of first and second non-linear optical layers of material with differing indexes of refraction. A layer of transparent semiconductor material is placed on the surface of the waveguide, which varies its index of refraction based on the potential applied to the electrodes. This innovation allows for dynamic control of phase matching in the waveguide.
Another significant patent is the "Frequency Doubling Optical Waveguide with Active Phase Matching." This device features a non-linear optical waveguide where phase matching is controlled by an electrically operated light modulator. The modulator is spaced apart from the waveguide and includes electrodes on a substrate, along with an elastomeric transparent gel that has a metallic coating. The application of voltage causes deformation in the gel, altering the gap and thus providing phase matching.
