Abstract

Official abstract text for this publication.

A method includes coupling an optical whispering gallery mode (WGM) resonator to an optical fiber by placing the optical fiber on the WGM resonator such that a contact portion of the optical fiber contacts the WGM resonator and two non-contact portions of the optical fiber extend beyond the contact portion, coupling the non-contact portions to locking screws, and adjusting positions of the locking screws to change a dimension of the contact portion.

First claim

Opening claim text (preview).

What is claimed is: 1 . A method of coupling a resonator and an optical fiber comprising: coupling an optical whispering gallery mode (WGM) resonator to an optical fiber by placing said optical fiber on said WGM resonator such that a contact portion of said optical fiber contacts said WGM resonator and two non-contact portions of said optical fiber extend beyond said contact portion, coupling said non-contact portions to locking screws, and adjusting positions of said locking screws to change a dimension of said contact portion. 2 . The method according to claim 1 , wherein said WGM resonator comprises a rod resonator and changing the dimension of said contact portion comprises varying a radius of said optical fiber with respect to a longitudinal axis of said rod resonator. 3 . The method according to claim 1 , wherein changing the dimension of said contact portion changes an effective coupling length of said WGM resonator to said optical fiber. 4 . The method according to claim 1 , wherein changing the dimension of said contact portion changes a coupling efficiency of the coupling of said WGM resonator to said optical fiber. 5 . The method according to claim 1 , wherein changing the dimension of said contact portion changes a transmission power of said optical fiber. 6 . The method according to claim 1 , wherein changing the dimension of said contact portion changes a loaded Q factor of said WGM resonator. 7 . The method according to claim 1 , wherein said contact portion comprises a tapered region of said optical fiber. 8 . The method according to claim 1 , wherein said non-contact portions comprise non-tapered regions of said optical fiber. 9 . The method according to claim 1 , further comprising using an adjusting screw to apply pressure on said optical fiber to readjust said dimension of said contact portion.
