摘要 | An optical isolator (10,20,200) for coupling light from a first waveguide to a second waveguide is disclosed. The optical isolator (10,20,200) utilizes a resonator (11,21,201) coupled to the first and second optical waveguides (12). The resonator (11,21,201) has a resonance at wavelength λ for light traveling from the first optical waveguide (13) to the second optical waveguide (12); however, the resonator (11,21,201) does not have a resonance at λ for light traveling from the second waveguide to the first waveguide. The resonator (11,21,201) can use a layer (22,275) of ferromagnetic material (15) in an applied magnetic field. The magnetic field within the ferromagnetic material (15) varies in strength and/or direction over the layer (22,275) of ferromagnetic material (15). The magnetic field can be generated by an external magnetic field that varies over the layer (22,275) of ferromagnetic material (15). Alternatively, the resonator (11,21,201) can include a layer (22,275) of ferromagnetic metal that overlies a portion of the layer (22,275) of ferromagnetic material (15) and a constant external magnetic field. |
其他摘要 | 公开了一种用于将来自第一波导的光耦合到第二波导的光学隔离器(10,20,200)。光隔离器(10,20,200)利用耦合到第一和第二光波导(12)的谐振器(11,21,201)。对于从第一光波导(13)传播到第二光波导(12)的光,谐振器(11,21,201)具有波长λ的谐振;然而,对于从第二波导传播到第一波导的光,谐振器(11,21,201)在λ处不具有谐振。谐振器(11,21,201)可以在施加的磁场中使用铁磁材料层(22,275)。铁磁材料(15)内的磁场在强度和/或方向上在铁磁材料(15)的层(22,275)上变化。磁场可以通过在铁磁材料(15)的层(22,275)上变化的外部磁场产生。或者,谐振器(11,21,201)可以包括铁磁金属层(22,275),其覆盖铁磁材料(15)的层(22,275)的一部分和恒定的外部磁场。 |
