    摘要: A tunable laser configured in a small package coupled to a printed circuit board. The tunable laser includes a housing with a volume formed by exterior walls. An electrical input interface is positioned at the first end of the housing. An optical output interface is positioned at the second end of the housing and configured to transmit a continuous wave optical beam. A semiconductor optical amplifier or gain chip produces an optical output beam, and an optical isolator is positioned directly downstream of the gain chip to prevent the incoming light from the downstream optics from reflecting back though the isolator and into the cavity of the laser. A beam splitter directs a portion of the light transmitted through the isolator back into the other end of the gain chip.

    摘要: A flip chip light emitting diode die (12) includes a light-transmissive substrate (20) and a plurality of semiconductor layers (22) are disposed on the light-transmissive substrate (20). The semiconductor layers (22) define a light-generating p/n junction. An electrode (30) is formed on the semiconductor layers (22) for flip-chip bonding the diode die (12) to an associated mount (14). The electrode (30) includes an optically transparent layer (42) formed of a substantially optically transparent material adjacent to the semiconductor layers (22) that makes ohmic contact therewith, and a reflective layer (44) adjacent to the optically transparent layer (42) and in electrically conductive communication therewith.

    摘要: A light emitting diode incorporating an active emitting layer (14) overlying a transparent substrate (10) is provided with a reflective diffraction grating (30) on the bottom surface of the substrate. Emitted light passing downwardly through the substrate is diffracted outwardly toward edges (21) of the substrate and passes out of the die through the edges. This effect enhances the external quantum efficiency of the diode.
