Abstract
A ring resonator includes a core. Both ends of the core in a lengthwise direction are connected to have a circular shape. The ring resonator further includes a cladding surrounding the core, a jacket surrounding the cladding and a sleeve surrounding a portion of the jacket. A portion of the core is exposed from the cladding and the jacket.
Claims7
A ring resonator, comprising:
- a core having two ends, wherein both ends of the core in a lengthwise direction are connected to have a circular shape;
- a cladding surrounding the core;
- a jacket surrounding the cladding;
- two sleeves, wherein each of the two sleeves surrounds a portion of the jacket;
- and
- a shrinking sleeve that is arranged to surround a portion where both ends of the core are connected to each other;
- wherein a portion of the core is exposed from the cladding and the jacket;
- wherein the shrinking sleeve is fitted to the jacket;
- and
- wherein the two sleeves are arranged at positions, respectively, which are symmetrical about the center of the ring resonator.
