    摘要: An angle cavity resonant photodetector assembly (8), which uses multiple reflections of light within a photodetector (14) to convert input light into an electrical signal. The photodetector (14) has a combination of generally planar semiconductor layers including semiconductor active layers (20) where light is converted into an electrical output. The photodetector (14) is positioned relative to a waveguide (10), where the waveguide (10) has a waveguide active layer (22) located between a pair of waveguide cladding layers (24) and (26) and includes a first end (28) for receiving light and a second end (30) for transmitting the light to the photodetector (14). The photodetector (14) has a first reflector (12) and second reflector (16) that provides for multiple reflections across the semiconductor active layers (20). In another embodiment, the waveguide (10) is positioned on one side of a cavity (58) and the photodetector (64) is positioned at an opposite end of the cavity (58) such that the light from the waveguide (10) travels across the cavity (58). The photodetector (64) is angled relative to the propagation direction of the light. The photodetector includes the first reflector (62) and the second reflector (68), which causes the light to pass through different areas of the photodetector active layers (72).

    摘要: A resonant photodetector assembly (10) which uses multiple reflections of light within a photodetector (20) to convert input light into an electrical signal. The photodetector (20) includes a combination of generally planar semiconductor layers including a photodetector active layer (36) where light is converted into an electrical output. The photodetector (20) further includes a first outer electrical contact layer (34) and a second outer electrical contact layer (42). A waveguide (22) is positioned on the photodetector (20) and has a waveguide active layer (26) positioned between a pair of waveguide cladding layers (24, 28), a first end (30) for receiving input light and a second end (50) for reflecting the light. A reflector (32) is positioned on the second end (50) of the waveguide (22) at an angle relative to a line parallel to the substrate (14), where the reflector (32) reflects the light received by the first end (30) of the waveguide active layer (26) towards the photodetector (20). A reflector (38) is positioned on the second outer layer (42) of the photodetector (20) and provides a reflective surface for reflecting the light within the photodetector (20).

    摘要: The invention relates to a method for fabricating III-V semiconductor micro-optical lenses for hybrid integration with micro-optical devices, where a micro-optical lens is formed from a semiconductor wafer by selectively etching a surface of the semiconductor wafer and a lens arm is formed from the semiconductor wafer on a surface opposite the surface by selectively etching the surface of the semiconductor wafer. The lens and lens arm are then cleaved from the substrate wafer and directly mounted to a micro-optical device. As a result of using III-V semiconductor material to form micro-optical lenses for hybrid integration to micro-optical devices of the same semiconductor material, thermal expansion stability is increased and efficient transfer of light between micro-optical lenses and micro-optical devices is achieved.
