Ultrahigh-speed all-optical half adder based on four-wave mixing in semiconductor optical amplifier

All-Optical Switching of Picosecond Pulses by Four-Wave Mixing in a Semiconductor Optical Amplifier

High-speed all-optical switching is demonstrated by four-wave mixing (FWM) of picosecond pulses using semiconductor optical amplifiers (SOA). A light source for measurement and switching in the 1.5 μm region is produced using a normal group velocity dispersion fiber and optical parametric oscillator. The output supercontinuum (SC) optical pulses, with a spectral width of approximately 300 nm, a...

Optical Demultiplexing Based on Four-Wave Mixing in Semiconductor Optical Amplifiers

Wavelength conversion by four-wave mixing in a folded-path, self-pumped semiconductor optical amplifier

WB7 Fig. 2. Spectra measured at the output of the SOA (0.1-nm resolution bandwidth). The upper shows the down-converted signals for the 30-, 20-, and 10-nm shifts (fromleft to right). For the smallest shift, we also show the pump and the input signal. The pump wavelength was tuned to lower wavelengths at constant power to achieve the larger shifts. The lower figure shows the up-converted signal...

Performance of Networks Using Wavelength Converters based on Four-Wave Mixing in Semiconductor Optical Ampli ers

| In this paper we examine the blocking performance of networks in which connections may be blocked due to either insuucient capacity or due to limitations in the transmission network. We use analytical expressions and network simulations to examine blocking in networks in which the quality of the received signal may be so poor that the connection is eeectively blocked. In particular, we apply ...
