Abstract
Disclosed are a light transmitting substrate, an array substrate, a color filter substrate and a display device. The light transmitting substrate includes a substrate body (10) comprising at least one intensifier layer (11) and at least one micro-ring resonate structure with a gain located in the intensifier layer (11). By arranging micro-ring resonate structure(s) with a gain in the substrate body (10), the light incident on the substrate is intensified upon passing through the micro-ring resonate structure so as to increase the intensity of the incident light.
Claims9
A light transmitting substrate comprising a substrate body, the substrate body comprises:
- at least one intensifier layer;
- and
- one a plurality of micro-ring resonate structures with a gain located in the intensifier layer,
- wherein each of the micro-ring resonate structures comprises a straight waveguide and a resonate ring which are coupled at a coupling end through a coupler such that a light wave input at an end of the straight waveguide has part of energy thereof coupled into the resonator ring at the coupling end and is output at the other end of the straight waveguide,
- wherein the micro-ring resonate structures are distributed in groups, and each group includes two micro-ring resonate structures which are arranged in opposite to each other such that the wave passes through the coupling ends in the two micro-ring resonate structures in opposite directions.
