Abstract

A stochastic method and its variants, differential evolution (DE) and micro-DE, were employed to optimize profiles of omnidirectional gratings for desired emittance spectra. Both narrow-band and broad-band infrared emitters were developed successfully from assigned profile types with different complexity and dimension constraints. The efficiency in determining profiles from each method was compared to demonstrate that the superiority of each method is dependent on the number of parameters (dimensions). The performance of the proposed emitters was further discussed considering the emission orientation and fabrication tolerance.
