Communication Lasers and Their Modulation Technology
摘要
In the field of optical communication, laser and its modulation bandwidth and modulation rate are very important for optical wireless communication. On the basis of reviewing the development history of communication laser and its modulation technology, this chapter introduces the work done by Xi’an University of Technology in this field; discusses the internal and external factors of nonlinear distortion of semiconductor laser; simulates the effects of various parameters of response characteristics, linearization compensation method, and power control system on the output light source of light emitting device; and analyzes the influence of temperature fluctuation on the output power of laser and modulation device.
