摘要	The present invention relates to an integrated optical ring resonator waveguide surrounded by an upper bus and a lower bus waveguide. A first resonant and intense optical wave is coupled into the upper bus whereas a second resonant optical wave is coupled into the lower bus. These resonant waves propagate from one bus to the other through the resonator in opposite directions. The first wave modulates the core refractive index of the resonator (Kerr effect) and thereby shifts the resonant conditions of the resonator. This results in the amplitude modulation of the second wave at its non-resonant port. Through this process, the optical amplitude modulation pattern of the first wave is transferred to the second wave. Optical wavelength switching is achieved when the waves have different wavelengths. In alternative embodiments and methods of driving the resonator, the resonator can achieve filtered wavelength tuning, add-and-drop multiplexing, space switching and intensity modulation.
其他摘要	集成光学环形谐振器波导本发明涉及由上部总线和下部总线波导包围的集成光学环形谐振器波导。第一谐振和强光波耦合到上总线，而第二谐振光波耦合到下总线。这些谐振波以相反的方向通过谐振器从一个总线传播到另一个总线。第一波调制谐振器的纤芯折射率（克尔效应），从而改变谐振器的谐振条件。这导致第二波在其非共振端口处的幅度调制。通过该过程，第一波的光学幅度调制图案被转移到第二波。当波具有不同波长时，实现光波长切换。在驱动谐振器的替代实施例和方法中，谐振器可以实现滤波波长调谐，分插复用，空间切换和强度调制。
主权项	A method of shifting the resonance curves of an optical ring filter using the Kerr effect comprising the steps of: Coupling an incident optical wave ("W.sub.inc") to one of the optical bus waveguides (the "buses") of an optical ring filter comprising two buses coupled to a ring waveguide resonator (the "ring"); Setting the value of the wavelength .lambda..sub.mc of W.sub.inc to one of the resonant wavelength values of the ring resulting in W.sub.mc propagating through the ring to the other bus; Increasing the optical intensity of W.sub.mc, causing a shift in the refractive index value of the ring due to the Kerr effect, up to a working point where the resonant intensity of W.sub.inc remains large enough to maintain the shift of the value of the refractive index of the ring; Resulting in a shift of the resonance curves of the ring, which are also the resonance curves of the optical ring filter.
