“…The aim of frequency stabilization is to lock the laser to a reference frequency. Some notable frequency stabilization methods include Zeeman frequency stabilization method 10 and polarization spectroscopy method. 11 However, both the power and stabilization methods require various optical devices and specific circuit systems, which cannot be used in highly integrated systems.…”

We propose a modeling methodology tailored to predicting the wavelength and power output from a distributed Bragg reflector laser for use in quantum measurements. The relationship between power, wavelength, current, and temperature is acquired with a genetic algorithm (GA). The function set and termination set for GA are determined from the physical mechanisms of laser current, temperature, and output performance. To verify the validity of the method, measured data are divided into a training group and a test group. The test results show that our models can accurately predict the value of power and wavelength at the given current and temperature, with the RMSE of 13.4 μW and 6.0 × 10 −5 nm, respectively. This method can help enhance the output performance of a laser. © The Authors. Published by SPIE under a Creative Commons Attribution 4.0 Unported License.
