چکیده
-In this paper, we propose the scheme for improving the characteristics of wavelength converter based on cross-gain modulation (XGM) in semiconductor optical amplifier (SOA). In front of the wavelength converter, a pre-amplifier is placed and adjusted to get optimal performance of wavelength converter in terms of bit error rate (BER) and corresponding power penalty. In the simulation, wavelength up conversion from 1548.51 nm to 1556.55 nm at 2.5Gb/s is performed and the result shows that a dynamic range is increased by amount of >4dB at 2dB of the power penalty.

We present the procedure for designing a high speed and low power all-optical analog to digital converter (AO-ADC), by integrating InGaAsP semiconductor optical amplifier (SOA) with InP based photonic crystal (PhC) drop filters. The self-phase modulation in the SOA can shift the frequency of the Gaussian input pulse. The two output PhC based drop filters are designed to appropriately code the f...

All optical wavelength conversion is demonstrated at 10 Gbit/s over a wavelength span of 10 nm without any bit loss by the use of Semiconductor Optical Amplifier (SOA) in a Mach-Zehnder configuration. These wavelength conversion architectures are implemented by using SOA cross-gain modulation (XGM) and cross-phase modulation (XPM) techniques. We have compared the results of both techniques on t...
