Abstract
A guided-mode resonant grating having a layered structure of a grating layer and a waveguide layer, wherein a refractive index difference between the grating layer and the waveguide layer is 0.1 or less, and light is made incident from a side of the waveguide layer, and a method for manufacturing the same, as well as an optical member or optical product including the guided-mode resonant grating.
Claims14
A guided-mode resonant grating comprising:
- a layered structure of a grating layer and a waveguide layer;
- and
- a substrate, the grating layer, and the waveguide layer in this order, wherein
- a refractive index difference between the grating layer and the waveguide layer is 0.1 or less, and light is made incident from a side of the waveguide layer, and
- a constituent material for the substrate, a constituent material for the grating layer, and a constituent material for the waveguide layer are the same.
