Abstract

This study presents a simple, single and an accurate computer-aided design model for quantum-cascade laser based on multi-layer perceptrons. Each critical quantity (optical gain, differential refractive index change, linewidth enhancement factor) that is used in the model requires long mathematical calculations with a strong background knowledge. In addition to that, these quantities use different theories, estimations and assumptions of some parameter values. The model tremendously decreases the computational time in the order of microseconds and is in very good agreement with previously published results.
