Claims15
A photodiode device comprising:
- a photosensitive diffusion junction within a single layer;
- and
- a resonant grating located within the single layer, wherein the photosensitive diffusion junction is located within the resonant grating.
A method of concentrating electromagnetic radiation in a photodiode device, wherein the photodiode device comprises a photosensitive diffusion junction within a single layer;
- wherein the photodiode device further comprises a resonant grating located within the single layer, wherein the photosensitive diffusion junction is located within the resonant grating, and wherein the method comprises the steps of:
- illuminating the photodiode device with electromagnetic radiation;
- and
- concentrating electromagnetic radiation incident on the photodiode device within the diffusion junction using the resonant grating.
