Paper Abstract
High contrast gratings (HCG) have various unique features such as broadband high reflections, high-Q resonance,
spatial control of optical phase and so on. We focus on the angular dependence of HCG, which can be managed by
designing grating parameters. The angular dependence of HCG is much larger than that of conventional quarter-wavelength
stack mirrors while keeping their broadband high reflections. The engineered angular dependence can be
useful for spatial mode MUX/DEMUX devices. A possibility of spatial mode demultiplexer based on HCG hollow
waveguides is suggested for use in optical interconnects with spatial mode multiplexing. Also, we discuss the transverse
mode control of HCG-loaded VCSELs.
