Abstract
An optical resonator includes a waveguide () formed by using an incidence side reflection film () and an emission side reflection film () arranged in parallel with each other and adapted to resonate light entering it by way of the incidence side reflection film () and adapted to propagate light formed and resonated so as to run through from the incidence side reflection () to the emission side reflection film (), a substrate () for forming the optical waveguide () on the top surface thereof and a first protection member () and a second protection member () corresponding to the material of the substrate () provided at an upper part of the waveguide () so as to make at least an end facet of each of the members form a plane () or () identical with the first end facet () or the second end facet (), whichever appropriate, of the substrate () including the light incidence end or the light emission end, whichever appropriate, of the optical waveguide () and the incidence side reflection film () and the emission side reflection film () are laid respectively on the formed planes (), ().
