Resonant reflector for use with optoelectronic devices

The optoelectronic device which prepares separation between the conduction layers which a resonance antenna reflector and an optoelectronic device adjoin is offered. It is separable by preparing a buffer layer or a cladding layer between the conduction layers which a resonance antenna reflector and an optoelectronic device adjoin. A cladding layer or a buffer layer is thick enough, or has a refractive index low enough compared with the refractive index of 導波路 of a resonance antenna reflector so that the energy in the evanescent tail of the waveguide mode in 導波路 may be prevented from advancing into the conduction layer which an optoelectronic device adjoins preferably on substance.
