PURPOSE: To economically manufacture a resonance device by forming it through a simple plastic processing. CONSTITUTION: A resonance device for forming coherent light having a relatively small frequency band, wherein pumping light is supplied to the resonance device, has two reflectors, for example Bragg reflectors, a gain medium is disposed between the reflectors, at least one reflector 5 is coupled to a gain medium 6, and at least one reflector 5 is constructed such that the reflector 5 is integrally structured within a optical waveguide 22, which consists of a polymer, coupled to the gain medium 6. |
