Title:
CIRCULAR RESONATOR, AND OPTICAL TRANSDUCER AND OPTICAL ELEMENT COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/190119
Kind Code:
A1
Abstract:
Disclosed are a circular resonator, and an optical transducer and an optical element comprising same. The circular resonator includes a first material, formed in a circular shape, including a plurality of nano holes and having a thermo-optic coefficient varying at a predetermined ratio according to temperature, and a second material having a thermo-optic coefficient varying in a direction opposite to the direction of change of the thermo-optic coefficient of the first material depending on temperature, the second material being filled in the plurality of nano holes, wherein an interval between the plurality of nano holes is formed at a pitch shorter than the wavelength of incident light.
