Application of VCSEL Laser Simulation Model in Home Fixed Network
Abstract:Aiming at the problem of ambient temperature in laser operation and device bandwidth, the model of optical power and current (L-I) of corresponding lasers and the characteristic curve model of voltage and current (U-I) in operation are proposed, the least square method and Gauss Newton method are used, the model is preliminarily solved and improved, and the temperature of the optimal laser working environment is finally obtained. Proposing a VCSEL model based on bandwidth (Small Signal Response Model), and considering the influence of laser temperature and bias current on device bandwidth, a nonlinear optimization method is used to calculate the bandwidth model and the conclusions can be drawn.
