Abstract
A theoretical formalism is established for double-layer (DL) antireflection coating (ARC) on a one-dimensional (1-D) photonic crystal (PC). Conventional DL-ARC for a bulk is equally applicable for a 1-D PC when the bulk substrate index is replaced with the optical admittance,which can be obtained from the electromagnetic Bloch waves of the infinite 1-D PC. Numerical calculations are performed for a model structure composed of GaAs and AlAs-oxide layers to confirm the validity of the theory. In terms of realization and practicality, this DL-ARC is expected to be superior to the single-layer version.
