PROBLEM TO BE SOLVED: To provide a micro optical resonator of light wavelength size used for a light-emitting element and a laser element wherein a light-emission intensity is raised in non-linearity of at least single-multiplication of an input power related to light emission intrinsic to a light-emission layer, for improved dependency of the light-emission intensity on the input power. SOLUTION: An optical active layer has a quantum confinement structure where micro particles about 1-10 nm in size, or quantum dot of material with large interaction between light and electron, are carried. The material with large interaction between light and electron has strong triggering power of an exciter while the quantum confinement effect bearing quantum dot is posed to generate a strong light emission. The strong light emission improves dependency of light-emission intensity on an input power.
