Simulation of Gain in Semiconductor Optical Amplifier Tension

The structure of an optical communication system similar to any other electrical connection system consists of several elements, including the transmitter (light source), medium (fiber optic) and receiver (optical detector) is. Standard single-mode fibers for data transmission at wavelengths normally used ۳۳/۱ micrometers and ۵۵.۱ micrometers. Optical fibers in the wavelength range of the losses are insignificant. Despite the low loss optical fibers for data transmission over long distances (more than ۵۰ km), the need to strengthen our optical pulses again. Therefore, the optical amplifiers are required. Semiconductor optical amplifier polarization is sensitive to the structure used to relieve tension. The advantages of optical communication devices compared to other communication devices, such as bandwidth, low weight, low-loss optical fiber, flexibility, safety data sent against electromagnetic interference and inexpensive noted.
