Patent number: 7075958Abstract: A method and apparatus are provided for monitoring an optical signal from a solid state laser. The method includes the steps of providing a planar substrate defined by opposing planar surfaces and a substrate edge that together define a substrate volume that is transparent to an optical signal from the solid state laser, disposing the solid state laser on one of the opposing planar surfaces the planar substrate such that a first portion of the optical signal travels directly through the planar substrate substantially orthogonal to the opposing planar surfaces and a second portion of the optical signal is reflected between the opposing planar surfaces of the planar substrate and passes out of the substrate through the substrate edge, and disposing an optical detector proximate the edge of the planar substrate to detect the second portion of the optical signal.Type: GrantFiled: June 2, 2004Date of Patent: July 11, 2006Assignee: Corona Optical Systems, Inc.Inventors: Randy W. Wickman, Gary T. O'Connor

Patent number: 6845211Abstract: A method and apparatus are provided for transmitting an optical communications signal. The method includes the steps of securing an optical device onto an optically transparent substrate with an optically transparent adhesive such that an axis of transmission of the optical device passes directly through the optically transparent adhesive and a portion of the body of the optically transparent substrate, darkening a portion of the optically transparent adhesive with a laser; and transmitting light from the optical device through the darkened portion of the optically transparent adhesive such that at least some of the light from the optical device is absorbed by the darkened portion.Type: GrantFiled: September 5, 2002Date of Patent: January 18, 2005Assignee: Corona Optical Systems, Inc.Inventors: Randy W. Wickman, Thomas Brockman, Steven C. Nelson

Patent number: 5048907Abstract: The invention is directed to laterally confined optical waveguide devices in semiconductors using quantum-well structures. An optical waveguide having a core comprising at least one quantum-well structure is interposed between first and second cladding regions such that an optical beam inserted into the core region spreads laterally with respect to a primary direction of the beam. Contacts are fabricated on the surface of the top cladding region and serve as means for applying an electric field to the core of the waveguide. The electric field induces a change in the refractive index of the portion of the quantum-well structure within the field. The change in the refractive index functions to laterally confine the propagation of the optical beam to the region of the core within the electric field, while maintaining a low loss transmission.Type: GrantFiled: February 23, 1990Date of Patent: September 17, 1991Assignee: Amoco CorporationInventors: Randy W.
