Patent Number Title Of Patent Date Issued
7309175 Reducing heating from non-coupled light in power transmitting optical fibers December 18, 2007
Method and apparatus for mounting an optical fiber for coupling to a high power light source, the fiber being secured to its mount with a low refractive index adhesive. The low refractive index adhesive serves to reduce the coupling of light traveling within the fiber to the fiber mo
6844992 Opto-mechanical platform January 18, 2005
An opto-mechanical platform for supporting truncated optical elements having at least one substantially flat side surface is disclosed. In one particular exemplary embodiment, the opto-mechanical platform may be realized as an apparatus for supporting truncated optical elements having
6741408 Thermally stable mounting for a diffraction grating device May 25, 2004
A wavelength division multiplexer (WDM) including a support structure that is coupled to at least one optical component. A diffraction grating is optically coupled to at least one optical component coupled to the at least one optical component. A frame is coupled to the diffraction g
6449097 Diffraction grating for wavelength division multiplexing/demultiplexing devices September 10, 2002
An improved diffraction grating for wavelength division multiplexing/demultiplexing devices is disclosed. The improved diffraction grating has a glass substrate, a polymer grating layer located adjacent to the glass substrate, and a metal coating layer located adjacent to the polymer
