摘要：

The relation between the output wavelengths of a laser array and the injection currents of all the channels is experimentally investigated and is found to be approximately linear. Based on this, the authors propose an optimization method of adjusting the wavelength distribution of the laser array by tuning the injection currents. In the proof-of-concept experiment, the linear wavelength residual is significantly reduced.
