A dual-channel, integrated, multiplexer, based on holographic Bragg reflector (HBR) devices and exhibiting flat-top, 4-nm-wide channels is demonstrated. Theory calibrated by the achieved performance indicates that HBR waveguide grating devices can be implemented to provide fully integrated and high performance multiplexer solutions for CWDM and FTTH applications. The enabling HBR devices can be regarded as mode-specific photonic crystals, i.e. photonic crystals whose spatial structure is tailored to interact with a specific signal mode or a very narrow range of such modes. Unlike standard bandgap-based photonic crystals, mode-specific photonic crystals may be effectively implemented with low-refractive-index-contrast and hence low-loss materials.
