Resonator and light emitting device using the same

摘要

Provided is a resonator using a three-dimensional photonic crystal. In the resonator, a range of choice of a resonance wavelength is wide and a desirable electric field distribution is obtained. The resonator according to the present invention includes a plurality of point defects provided in the three-dimensional photonic crystal. At least one of the plurality of point defects does not include a eigenmode in a photonic band gap of the three-dimensional photonic crystal.
