Embodiment Construction
[0044] The present invention will be further elaborated below through specific embodiments in conjunction with the accompanying drawings.
[0045] Such as figure 1 As shown, the one-dimensional photonic crystal edge-emitting laser based on organic semiconductors of the present embodiment includes: a substrate 1, a gain medium 2, a total reflection structure 3, a partial transmission structure 4, a mode selection structure 5 and a pump source 6; wherein, in The upper surface of the substrate 1 is spin-coated with an organic semiconductor luminescent material, the refractive index of the substrate is lower than that of the organic semiconductor luminescent material; the organic semiconductor luminescent material is etched to form a ridge-shaped gain medium 2 on the substrate as a ridge-shaped waveguide; Three photonic crystal gratings parallel to each other are respectively formed on the gain medium 2, and the photonic crystal gratings are perpendicular to the surface of the sub...
