    摘要： Our invention relates generally to an optical switch (31) and an optical router (10) to rapidly route signals from particular channels (22, 24) within an optical band by using optical switches (20) which utilize a controlled whispering gallery mode (WGM) resonance of dielectric microspheres (S1, S2, S3) to optically switch signals. Another invention relates to optical filters which use a WGM resonate structure (150) to isolate and switch specific optical signals between waveguides (F1, F2). In other inventions, the filter (100) is switched “on/off” by signal loss within a WGM resonate structure (150) which disrupts the WGM resonance; the filter (100) isolates and switches a specific wavelength signal from among a group of signals of different wavelengths; and is switched “off” by adjusting the index of refraction of the resonate structure to become substantially similar to the index of refraction of the surrounding medium.

    摘要翻译： 本发明一般涉及光开关（31）和光路由器（10），用于通过使用光开关（20）来快速地从光频带内的特定通道（22,24）传送信号，所述光开关利用受控的耳语画廊模式（WGM ）电介质微球的共振（S 1，S 2，S 3）来光学切换信号。 另一个发明涉及使用WGM谐振结构（150）来隔离和切换波导（F 1，F 2）之间的特定光信号的滤光器。 在其它发明中，滤波器（100）通过在WGM共振结构（150）内的信号损失被切换为“开/关”，这破坏了WGM谐振; 滤波器（100）从不同波长的一组信号中隔离并切换特定的波长信号; 并且通过调节谐振结构的折射率而变得基本上类似于周围介质的折射率而被切换为“关闭”。

    摘要： An optical switch and optical router to rapidly (in the range of nanoseconds to picoseconds) route signals from particular channels within an optical band by using optical switches which utilize a controlled whispering gallery mode (WGM) resonance of dielectric microspheres to optically switch signal by virtue of their evanescent waves.
