摘要： A surface emitting light emitting device with a semiconducting substrate, a semiconducting mirror stack positioned on the substrate surface, a spacer layer positioned on the mirror stack, an active region positioned on the spacer layer, a second spacer layer positioned on the active region, a second semiconducting mirror stack positioned on the second spacer layer, and a top contact layer positioned in contact with the second semiconducting mirror stack. The active region includes multiple quantum wells each having a different transition wavelength and positioned on the spacer layer with the quantum well possessing the longest transition wavelength located closest to the spacer layer and additional quantum wells of the multiple quantum wells positioned in order of decreasing transition wavelength so that the sum of the emission from all of the quantum wells results in a broad and uniform output emission spectrum.

摘要： An interface between a laminated polymer optical waveguide (15) and an electronic device (39). The interface does not degrade the desirable properties of the optical waveguide (15), is simple, is low cost, and is compatible with integrated circuit technology as well as optical and electrical connectors (41,42,43,46). The interface includes at least one vertical cavity surface emitting laser or photosensitive diode (11,37) mounted above the surface of the optical waveguide (15). A mirror (21) positioned at an angle with respect to the optical waveguide (15) serves to reflect light between either the vertical cavity surface emitting laser or photosensitive diode (11,37) and the optical waveguide (15). At least one microstrip line (16) couples electrical signals between the vertical cavity surface emitting laser (11,37) and the electronic device (39).

摘要： A method is provided for partially collecting light from a polymer waveguide (11, 56). A polymer waveguide (11, 56) is provided, through which a light signal (17) is traveling. A faceted groove (28) is placed in the polymer waveguide (11, 56), thereby reflecting a controllable portion of the light (22) that is traveling through the polymer waveguide (11, 56) from the facet (21) at an oblique angle. Typically, the reflected light is directed into a photodetector (24, 41), which is included into an integrated circuit (52, 53) on a substrate (51).
