Polarization Analyzer Based Detection Schemes for Pol-Mux Self-Coherent Single Sideband Optical Transmission
Researchers at the University of Arizona have developed an orthogonal frequency division multiplexing (OFDM) optical communication system for access networks that can work in a direct receiver mode and in a coherent receiver mode. Compared to currently available OFDM products, the novel system has fewer components and is simpler to set up.

An FPGA Implementation of a Gb/s OFDM Transmitter and Receiver for Fiber Telecommunication Applications
University of Arizona researchers have invented a Field-Programmable Gate Array (FPGA) implementation of Orthogonal Frequency Division Multiplexing (OFDM) transmitter (Tx) and receiver (Rx). The design has two variants. One for direct detection OFDM and one for coherent OFDM based on self-coherent reception.
This technology will allow for easier,...

High Efficient Continuous Wave and Mode-Locked Lasers Powered by Solar Energy
Faculty at the University of Arizona have developed a compact, efficient solar-powered laser that uses triple junction photovoltaic cells to power semiconductor and mode-locked lasers. Existing solar-pumped lasers use an arc-metal-halide lamp pump that requires bulky concentrating optics and is power inefficient. By using a triple junction photovoltaic...
