PHOTONIC INTEGRATED WAVEGUIDES WITH LOW ABSORPTION LOSSTech for Transfer TTO 17-12-2015 Asymmetric twin waveguides (ATG) present a promising method for optoelectronic integration by needing only a single epitaxial growth step and a simple fabrication process for even the most complex photonic integrated circuit (PIC) design. This invention provides an ATG structure that employs quantum-well intermixing (QWI) to reduce absorption loss normally encountered in the movement of light between waveguides. QWI relies on the mixing of the quantum well and barrier materials of an active region, resulting in an alloy whose bandgap is intermediate between that of the wells and barriers.

PHOTONIC CRYSTAL PRESSURE SENSORTech for Transfer TTO 18-12-2015 The present invention provides a microscale pressure sensor that exhibits high sensitivity in a small form factor. The sensor is a bridged device in which a photonic crystal waveguide, surrounded by a photonic crystal slab, is suspended over a dielectric substrate. Under applied pressure, the photonic crystal waveguide is deflected toward the substrate, causing a decrease in optical transmission across the waveguide due to the coupling of the evanescent field of the guided mode to the dielectric substrate. The waveguide can be coupled to a photonic crystal microcavity, which increases evanescent coupling. This inventive design enables a higher sensitivity and better tolerance to manufacturing imperfections. Photonic Crystals Waveguides Tell me more |

FIBER-WAVEGUIDE EVANESCENT COUPLERTech for Transfer TTO 18-01-2016 This invention presents a new technique for evanescent coupling of an optical fiber to a waveguide. A portion of the fiber cladding near the end of the fiber is removed and the fiber core is placed directly on top of a waveguide formed on a substrate. The fiber core overlaps with the waveguide to enable optical evanescent coupling via side surfaces of the fiber core and the waveguide. The technique yields a large alignment tolerance, hence is relatively simple to implement, and can significantly lower the cost of optoelectronic packaging. Fiber Optics Waveguides Tell me more |
