Abstract

The invention discloses a selectively converging optical device comprising a selective reflecting coating, an upper light guide layer, a light-to-frequency conversion coating, a lower light guide layer, a reflective layer and an encapsulation protective layer, which are overlapped sequentially from top to bottom. One side of the optical device is an emergent surface, and the other sides of the optical device are provided with the reflective layer and the encapsulation protective layer from the inside to the outside. The selective reflecting coating consists of any one selected from one-dimensional photonic crystals, two-dimensional photonic crystals and three-dimensional photonic crystals. The light-to-frequency conversion coating consists of an organic or inorganic fluorescent conversion material or semiconductor nanometer crystals for converting incident light into isotropic light with the same wavelength for being emitted. The forbidden-band wavelength of the photonic crystals is the same with the wavelength of the emitted light of the light-to-frequency conversion coating. The selectively converging optical device can be used for converging light and emitting light with the same wavelength on the emergent surface.

Description

technical field [0001] The invention relates to an optical device capable of selecting wavelengths for converging and outputting. The optical device can convert incident light on a light-receiving surface into light of a specific wavelength, and converging and outputting it on a fixed end face of the optical device. Background technique [0002] The convergence of light is of great significance to optical devices and light energy utilization. The convergence of light in the sense of traditional geometric optics usually has two forms: one is through transmission and refraction convergence, that is, using a certain geometric shape lens or Fresnel lens to refract light, and regularly changing the direction of propagation of parallel light so that in Focus creates convergence. One is through reflection and convergence, that is, using concave mirrors such as parabolic mirrors and spherical mirrors to reflect incident parallel light so that the light converges at the focal point....
