Abstract
Semiconductor optical amplifier had been studied theoretically using the traveling wave equation. The study took into consideration the many parameters that could affect the operation of amplifier, such as mole fraction, noise figure and material gain have been studied theoretically for the suggested amplifier in the wavelength of 1.55 m. The results show that gain material peak was shifted when injected current and wavelength were varied. An interesting result of the noise figure was found to be minimum at the operating wavelength of 1.55 m.
Keywords: Amplifier noise, noise, noise figure, noise measurement, wideband semiconductor optical amplifiers.
