Abstract
Various embodiments of the present invention are directed to a photodiode module including a structure configured to selectively couple light to a dielectric-surface mode of a photonic crystal of the photodiode module. In one embodiment of the present invention, a photodiode module includes a semiconductor structure having a p-region and an n-region. The photodiode module further includes a photonic crystal having a surface positioned adjacent to the semiconductor structure. A diffraction grating of the photodiode module may be positioned and configured to selectively couple light incident on the diffraction grating to a dielectric-surface mode associated with the surface of the photonic crystal. In another embodiment of the present invention, a photodiode apparatus includes multiple, stacked photodiode modules, each of which is configured to selectively absorb light at a selected wavelength or range of wavelengths.
