Abstract :
The investigated intra-cavity-contacted oxide-confined vertical-cavity surface emitting laser (ICOC-VCSEL) has 980 nm wavelength and 10 GHz modulation bandwidth. The modulation dynamics of VCSEL with multiple quantum wells is modeled by coupled rate equations, which describe the carrier number in the SCH layer and the quantum well, and photon number in the mode cavity (Nguyen, et. al., 1995) and contains 10 model parameters.The parameter extraction model consists of maximum parameters, which can be described analytically. Calculated parameters have physically reasonable values and exhibit very good agreement with measured data in the linear and weakly nonlinear regimes.
