High Speed VCSEL for 1300 nm Optical Network

Fiber optical transmission is increasingly applied to computer network, secure telecommunication systems, military aircraft, and even in missile guidance systems. 1300 nm vertical cavity surface-emitting lasers (VCSEL) are becoming a prefered technologyfor transceivers in short- and medium-haul, enterprise and metro data network. There is significant interest in using diluted nitride GaInNAs as active medium at this wavelength due to its high T0 and lattice-matched reflector stacks. We propose a newdesign, the index guided, implanted struture (I^2-VCSEL) that could lead to far superior performance than the conventional design. Of its advantages particularly notable is the reduced p-layer absorption which is a significant issue in these longerwavelength regions. In Phase I the proposed device structure will be fabricated and evaluated, to demonstrate its potential advantages. Process will be furhter optimized in Phase II leading to demonstration of high speed single mode fibertransmission.Optical fiber data transmission, optical scanners, environmental sensing, optical computing
