Step-by-step parameter-extraction method for high-speed vertical cavity laser's rate-equation model

Abstract

Values for parameters in a rate equation description of a vertical-cavity surface emitting laser (VCSEL) must be appropriately selected in order to obtain agreement between the calculated and measured results regarding system performance. Here, a technique is described for readily extracting values of the rate equation parameters using measurements of light-current and small-signal modulation characteristics for a bias current well above the threshold current. The calculated and measured data for the device are in good agreement.
