    摘要: Methods and apparatus for reducing the oscillation of a MEMS actuator. In one embodiment, a driving signal is generated to adjust the MEMS actuator through a set of driving wires coupled to the MEMS actuator. A motion-induced signal from the set of driving wires coupled to the MEMS actuator is received in response to the driving signal. The motion-induced signal is filtered to generate a filtered motion-induced signal. The filtered motion-induced signal is amplified to generate an amplified filtered motion-induced signal. The driving signal is adjusted based on the amplified filtered motion-induced signal to reduce the oscillation of the MEMS actuator.

    摘要: An optical splitter has a main branch coupled to a number of tributary branches. The main branch includes a light-absorptive core and a light-reflective grating. The absorptive core can absorb light arriving from the tributary branches and transmit light arriving from the main branch to the reflective grating. The reflective grating can reflect light from the main branch back through the absorptive core to the main branch. Light arriving from the tributary branches exchanges mode with light reflected by the reflective grating.

    摘要: Optical cross connects and methods for use therewith are described herein. In an embodiment, an optical cross connect includes first and second mirror arrays, first and second light sources that respectively emit first and second color coded light beams (e.g., each of which includes red, green and blue light), and first and second cameras configured to respectively capture first and second color images of the first and second color coded light beams reflected respectively from the first and second mirror arrays. The optical cross connect also includes a controller configured to perform closed loop feedback control of the first and second mirror arrays, based on the first and second color images, when the controller controls how optical signals are transferred between individual optical fibers in a first bundle of optical fibers and individual optical fibers in a second bundle of optical fibers.
