Abstract

The objective of this research is design of nanophotonic resonance devices including filters, mirrors, and polarizers with minimal materials requirements. Thus, single-layer, silicon-based, two-dimensional resonant leaky mode elements implemented with periodic waveguide layers are presented. We apply particle swarm optimization to design these devices. Example results include a broadband reflector with center wavelength of 1700 nm and bandwidth of ~161 nm across which the zero-order reflectance exceeds 99%. An efficient bandpass filter with spectral width of ~2 nm at 1550 nm central wavelength is realized. The versatility of the leaky-mode resonance concept is rendered clearly as these single-layer devices consist of identical materials yet provide completely different spectral expressions. Particle swarm optimization is thus effective for this class of problems and straightforward in implementation.
