Abstract

Guided-mode resonances at the gamma-point are characterized via normal-incidence transmission measurements through photonic crystal slabs. By placing the photonic crystal slab between two orthogonally oriented polarization filters, direct light transmission is suppressed. Only light coupling to the guided-mode resonances is observed in transmission. Transmission properties of linear, quadratic, and hexagonal photonic crystal slabs are investigated. Experimental results are compared to finite-difference time-domain simulations.
