The picosecond decay of carriers in InGaAs, following photo excitation at photon energies just above the band edge, has been measured. A mode-locked neodymium:yttrium aluminum garnet pumped optical parametric amplifier provided the tunable, 35-ps pulses for excite-probe measurements. At carrier densities in excess of 1018 cm−3 Auger processes are found to dominate the carrier recombination. We determine an Auger rate of 2.5±0.5×10−28 cm6 s−1.
The algorithmic, electronic, and optical aspects of the implementation of a perfect-shuffle interconnected bitonic sorter are analyzed. The performance metrics such as the bit output data rate and the power consumption of the system are quantified. The sorting module is designed to demonstrate the parallel nonlocal interconnection of smart-pixel arrays and the use of optical-image control masks in a functioning information processor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
