Bayesian optimization refines PCSEL design for optical communication

Researchers have developed a reliability-aware Bayesian optimization method to refine the design of 1310 nm photonic-crystal surface-emitting lasers (PCSELs). This approach couples a finite-difference time-domain solver with a Bayesian optimization loop, updating a surrogate model with each simulation to select the next geometry. The method combines wavelength and beam-quality requirements with a reliability-adjusted metric, significantly increasing the yield of high-Q PCSEL candidates compared to traditional methods like differential evolution and Latin-hypercube sampling.
