Summary: | PROBLEM TO BE SOLVED: To make an optical resonance frequency variable and to stabilize the optical resonance. SOLUTION: A resonator 300, for example, a silica microsphere or disk, is used between two optical fiber cables 500, 502 to form an add/drop filter. The resonator 300 is resonant with a frequency to be added or dropped. In this way, only that particular channel is added or dropped as needed. The resonator 300 is coated with a coating with a variable refractive index and its resonance frequency is changed by changing the refractive index. Also the optical resonance of the resonator 300 is monitored and feedback control is applied to the wavelength of the optical resonance. COPYRIGHT: (C)2005,JPO&NCIPI |
