<p><P>PROBLEM TO BE SOLVED: To provide an optical resonator precisely tunable so as to satisfactorily differentiate frequencies, a method for temporarily tuning such an optical resonator, and an optical demultiplexer containing such an optical resonator. <P>SOLUTION: The tuned optical resonator comprises a substrate, an input side waveguide and an optical resonator waveguide formed on the substrate. The optical resonator waveguide has a resonance frequency and presents a first refractive index, temporarily presents a second refractive index in response to application of laser energy, and temporarily resonates with a resonance frequency while the laser energy is applied. <P>COPYRIGHT: (C)2004,JPO</p> |
