Paper Abstract

Deducing the design parameters of semiconductor lasers from a desired spectrum and light-current (L-I) curve, etc., i.e. the inverse design technique, is highly demanded both academically and in industry. Here, we propose an approach to obtain the inverse design of a laser by combining the deep learning algorithm and the particle swarm optimization (PSO) method. The deep-learning neural network (NN) is trained by the traveling-wave model (TWM) calculated database, and is used to predict the output power for any given new set of design parameters. The standard deviation of the NN approximation can be as low as 0.31mW, and the CPU time as fast as 0.07s, which is much more efficient compared with the TWM numerical algorithm (of CPU time 125.57s), for the same L-I curve calculation. By combining NN with the PSO algorithm, laser parameters can be inversely designed and optimized according to the given/desired L-I curve. Speed of the this process can be improved by about 17,500 times, and the designed parameters are found to be close to their preset values in the test, which indicates its possibility to solve the nonlinear problem for the semiconductor laser process.
