| 摘要 |
The optical hybrid device includes input optical fiber(s), output optical fiber(s), a lens, a broadband or passband filter, a movable mirror, and an actuator operative to move the mirror or the filter. Depending on a voltage applied to the actuator, the actuator selectively sets the mirror or filter to each of a plurality of positions, so that selected portion(s) of radiation from one or more input beams carried by the input optical fiber(s) are conveyed to the output optical fiber(s); whereby the device performs two or more of the functions of wavelength division multiplexing or demultiplexing, attenuation, switching, filtering and tapping functions.
