Abstract
In order to design and optimize high frequency performances of laser diodes,accurate extraction methods for the rate equation parameters are very important.A method for the rate equation parameter extraction for long-wavelength and high-bandwidth buried tunnel junction vertical-cavity surface-emitting lasers is presented.This method bases on the threshold current,output power,resonance frequency,damping factor and nonlinear effect of the gain compression factor under high bias currents.By fitting the chip frequency responses with different bias currents,resonance frequency and damping factor values can be obtained.Finally,by considering gain compression factor and nonlinear fitting resonance frequency and damping factor values under different currents,parameters of rate equation model can be extracted.
