Optical data path comprising a vertical cavity surface emitting laser VCSEL and a resonant cavity photo-diode RCPD

摘要

Optoelectronic devices such as VCSEL and RCPD devices that have integrated resonant reflectors. The integrated resonant relfector may be made conductive so that bias current can pass therethrough. This may allow more flexibility in the design of the VCSEL and RCPD devices. Since making the resonant reflector more conductive typiically reduces the overall reflectivity of the resonant reflector, the resonant reflector may be provided in combination with a Distributed Bragg Reflector (DBR) mirror to achieve the desired overall reflectance for a VCSEL or RCPD design. A broad bandwidth resonant reflector may also be provided. The bandwidth may be sufficiently wide to increase the reliability of data communication between such devices, and may be sufficiently narrow to maintain adequate mode control and mode stability. These devices may be used to support polarization-, space- and/or wavelength-division multiplexing applications.
