FOMs extraction for quantum-well lasers and low-noise amplifiers with a modified genetic algorithm technique

In this work, a modified GA, including search-space separation strategy and local-minima-convergence prevention process, is developed to extract the significant FoMs for the feasible QW lasers and LNAs in future new integrated systems. The multi-parameter extraction strategy is dependent on succinctly associating the analytic equation with the global numerical analysis. Results are demonstrated on state-of-the-art 1060 nm InGaAs QW lasers and advanced 0.35 μm SiGe HBT-based LNAs.
