    • An optical filter is disclosed which uses an integral GT resonator and fiber coupler to form a Michelson interferometer. The coupler will divide the light into two arms, with one arm being reflected by a high reflectance mirror, and the other arm being reflected by a GT resonator. The size of the arms and the spacing of the resonator determines the filtering characteristics of the filter. Tuning the filter is accomplished by illuminating a photosensitive fiber material that is used to form a portion of the filter. Illumination causes the refractive index of the material to change, and thereby changes the effective length of the fiber, which in turn adjusts or tunes the characteristics of the filter.
    • 公开了一种使用集成的GT谐振器和光纤耦合器来形成迈克尔逊干涉仪的滤光器。 耦合器将光分成两个臂,一个臂由高反射镜反射,另一个臂由GT谐振器反射。 臂的尺寸和谐振器的间距决定了滤波器的滤波特性。 通过照射用于形成过滤器的一部分的感光纤维材料来实现调谐过滤器。 照明使材料的折射率发生变化,从而改变光纤的有效长度,从而改变滤光器的特性。

    • An optical apparatus comprises a planar optical waveguide having at least two reflectors. The planar optical waveguide substantially confines in at least one transverse spatial dimension optical signals propagating therein, and the reflectors define an optical resonator that supports at least one resonant optical cavity mode. At least one of the reflectors comprises a set of diffractive elements arranged: so that an optical signal in one of the resonant optical cavity modes is successively incident on the diffractive elements; so as to exhibit a positional variation in amplitude, optical separation, or spatial phase; and so as to apply a transfer function to the optical signal successively incident on the diffractive elements. The transfer function is determined at least in part by said positional variation in amplitude, optical separation, or spatial phase exhibited by the diffractive elements.
    • 光学装置包括具有至少两个反射器的平面光波导。 平面光波导基本上限制在其中传播的至少一个横向空间维度的光信号,并且反射器限定支持至少一个谐振光腔模式的光学谐振器。 所述反射器中的至少一个包括一组衍射元件,所述衍射元件被布置成:使得所述谐振光腔模式中的一个中的光信号被连续地入射到所述衍射元件上; 以显示幅度,光学分离或空间相位的位置变化; 并且对连续入射到衍射元件上的光信号应用传递函数。 传递函数至少部分地由所述衍射元件显示的振幅,光学分离或空间相位的位置变化确定。
