Semiconductor Devices for All Optical Signal Processing: Just How Fast can They Go?
No full textSeveral different semiconductor device structures for accomplishing all-optical signal processing have been proposed, but they nearly all employ the semiconductor optical amplifier (SOA) as a central element. In this talk we will discuss the physical processes in SOA's that are important in determining the speed of SOA based switches. We shall consider both devices based on incoherent processes, such as optically induced cross-gain and cross-phase modulation as well as devices employing coherent four-wave mixing
Dispersion-induced non-linearities in semiconductors
No full textWe show that index dispersion in connection with the standard (slow) saturation of the medium due to carrier density changes, lead to ultrafast gain and index dynamics. Analytical formulas are derived, and it is shown that these new contributions may dominate experimentally observed results
