Near-infrared photodetectors and optical interconnects fabricated monolithically on silicon
Near-infrared photodetectors and optical interconnects fabricated monolithically on silicon
Integrating CMOS with optical communications technology on a silicon wafer can be achieved with the fabrication of a near-infrared photodetector in silicon. The camel diode photodetector has been developed to detect infrared light at optical communications frequencies. This all-silicon device uses free carrier absorption to excite majority carriers, which are emitted over a potential barrier. In addition, a novel optical interconnect has been developed which can incorporate the camel diode, to provide optical containment without silicon-on-insulator technology. Electrical and optical isolation from the substrate is achieved by undercutting the waveguiding region and thermally oxidizing the supporting trunk.
