Verilog-a Implementation of a 2d Spatiotemporal Vcsel Model for System-oriented Simulations of Optical Links
نویسنده
چکیده
An implementation of a highly efficient spatiotemporal vertical-cavity surface-emitting laser (VCSEL) model in the circuit simulation environment of Cadence is presented. The VCSEL model, based on a set of modified rate equations, is written in Verilog-A. It enables the association of the VCSEL model with transistor-level models of the driver and detector circuits. Furthermore, the spatiotemporal nature of the model allows the generation of multimode responses and corresponding far-field intensity profiles, which can be used to investigate fibre coupling and propagation mechanisms. An optimization of the VCSEL drive signal performed using the built-in optimizer of Cadence is presented. © 2003 Wiley Periodicals, Inc.

VISTAS: A Comprehensive System-Oriented Spatiotemporal VCSEL Model
We propose a highly efficient spatiotemporal verticalcavity surface-emitting laser (VCSEL) model aimed at optimizing entire optical links. It is based on two-dimensional (2-D) rate equations, which allow the computation of dynamic gain competition resulting from inhomogeneous field and carrier spatial distributions in the cavity. The equations are mathematically transformed so as to remove any ...
