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: A planar semiconductor laser having low thermal and series resistance is fabricated. The semiconductor laser has an optical waveguide and a lateral current injection path provided by a conductive region. The conductive region disorders the active region and the first 1/4 wave stack of the laser, which reduces the reflectivity, therefore allowing control of the optical waveguide independent of the current flow. By forming the conductive region, the laser of the present invention can have stable optical characteristics and a bigger emission spot due to the weak built-in waveguide, thus resulting in the formation of a device having high output and a low thermal and series resistance.

摘要: A vertical cavity surface emitting laser (VCSEL), comprised of a first 1/4 wave stack, an active layer and a second 1/4 wave stack, is integrated with a heterojunction bipolar transistor (HBT). The HBT is partially or fully positioned within either the first or the second 1/4 wave stack of the VCSEL. This method improves the planarity of the device, thus allowing for high performance devices to be fabricated. A top or bottom emitting device may be fabricated with the second 1/4 wave stack comprised of dielectric layers or semiconductor epitaxial layers.

摘要: Patterned-mirrors for VCSELs are fabricated by forming a first mirror stack of a plurality of pairs of relatively high and low index of refraction layers of AlGaAs, forming an active region of aluminum-free material on the first mirror stack, and forming a second mirror stack of a plurality of pairs of relatively high and low index of refraction layers of AlGaAs. The second mirror stack can be selectively etched to the active region by utilizing the aluminum-free active region as an etch stop.

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).
