摘要： An apparatus and method of controlling optical loss in an optical switch to equalize optical power or loss in a group of optical signals in an optical transmission system relatively insensitive to mechanical vibration. In one embodiment a group of optical signals is input into an optical switch and selected optical signals are variably attenuated using synchronized control to two mirrors in order to provide more uniform power distribution among the group of optical signals without enhancing vibration sensitivity of the optical switch.

摘要： An optical switch having switch mirror arrays controlled by scanning beams that reduce the amount of electrical connections required and reduce the complexity for constructing large optical switches. Movement of the switch mirror arrays is controlled by one or more scanning beams. The optical switch includes one or more arrays of optical switch inputs and outputs and one or more arrays of movable mirrors to direct light beams from the optical switch inputs to the optical switch outputs. The optical switch also includes one or more control elements to control the movable mirrors based on scanning beams directed to the one or more control elements.

摘要： An optical switch for routing arbitrary wavelengths between optical fibers in optical networks. The optical switch may include a highly wavelength dispersive element together with a spatially dispersive element to separate the wavelengths. Broadband switch inputs and outputs may be provided for adding and dropping arbitrary wavelengths at each node of the network. Fiber demultiplexers and multiplexers may also be used to reduce the impact of mirror array yield on switch functionality.
