Abstract: This invention provides a novel method and apparatus which use a wavelength-dispersing means such as a diffraction grating (220) to spatially separate a multi-wavelength optical signal along with a reference signal by wavelength into multiple spectral channels and a reference spectral component in a spectral array with a predetermined relative alignment. By aligning the reference spectral component at a predetermined location, the spectral channels simultaneously impinge onto designated locations, e.g., on an array of beam-receiving elements positioned in accordance with the spectral array. The reference spectral component may be further maintained at the predetermined location by way of servo-control (260), thereby ensuring that the spectral channels stay aligned at the designated locations. The present invention can be used to construct a new line of servo-based optical systems, including spectral power monitors and optical multiplexers/demultiplexers, for WDM optical networking applications.

Abstract: The present invention provides a method and apparatus (100) for optical spectral power monitoring employing novel frequency-division-multiplexing detection schemes. The optical spectral power monitoring apparatus (100) of the present invention uses a wavelength-dispersing means (e.g., a diffraction grating) (120) to separate a multi-wavelength optical signal into multiple spectral channels, and an array of beam-modulating elements (e.g., micromirrors) (140) positioned such that each beam-modulating element receives a unique one of the spectral channels. The beam-modulating elements are individually controllable such that the optical power levels of the spectral channels coupled into an output port (110-2) carry distinct dither modulation signals. By performing a synchronous detection of the dither modulation signals, in conjunction with a predetermined calibration table, an optical power spectrum of the multi-wavelength optical signal can be derived. Such dither modulation signals may also be used as "identification markers" (or frequency tags) for identifying individual spectral channels in an optical networking application.

Abstract: This invention provides a novel wavelength-separating-routing (WSR) apparatus that uses a diffraction grating to separate a multi-wavelength optical signal by wavelength into multiple spectral characters, which are then focused onto an array of corresponding channel micromirrors. The channel micromirrors are individually controllable and continuously pivotable to reflect the spectral channels into selected output ports. As such, the inventive WSR apparatus is capable of routing the spectral channels on a channel-by-channel basis and coupling any spectral channel into any one of the output ports. The WSR apparatus of the present invention may be further equipped with servo-control and spectral power-management capabilities, thereby maintaining the coupling efficiencies of the spectral channels into the output ports at desired values. The WSR apparatus of the present invention can be used to construct a novel class of dynamically reconfigurable optical add-drop multiplexers (OADMs) for WDM optical networking applications.

Abstract: A method and an apparatus for switching a beam from a first port to a second port in an optical switch are described. Switching is performed by a single-axis beam steering element and one or more actuatable beam diffraction devices. Each beam diffraction device is actuatable between diffracting and non-diffracting states. Each beam diffraction device is configured to deflect the optical beam when in the diffracting state such that at least part of the optical beam is diffracted outside a detection area of a column of I/O ports. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

Abstract: Optical switches can include collimator elements that accommodate two or more optical ports. This increases the number of ports the switch can accommodate without having to increase the size of other optical components within the switch. Separate deflectors can be used to accommodate optical signals from two different groups of ports. In some embodiments cross-coupling of signals between the two groups can be accomplished through use of re-direction optics.

Abstract: Methods for adjusting dither amplitude for MEMS mirrors in optical switches and optical switches employing such a method are disclosed. A dither amplitude of one or more MEMS mirrors may be adjusted in an optical switch having an input port, and an array of one or more MEMS mirrors that can be selectively optically coupled to one or more of optical input/output (I/O) ports. Digital- to-analog (DAC) settings for positioning mirrors are used to determine a dither amplitude for one of the MEMS mirrors positioned to couple optical signals to an output port at a position x. The servo control assembly includes memory containing digital-to-analog converter (DAC) settings for positioning each mirror in an open control loop as a function of a port position x. The servo control assembly is programmed to adjust dither amplitude of one or more of the MEMS mirrors using the stored DAC settings.

Abstract: A system and method for canceling disturbance in a MEMS device. The system 2 00 includes a MEMS device 203, which may include a substrate 205 and a pluralit y of individually movable MEMS elements 203-1 through 203-N, and a control assembly 207. The optical system 200 may be utilized in and/or form a portio n of any optical apparatus employing an array of MEMS devices. The control assembly 207 uses feed-forward control signals to cancel disturbance in the MEMS device 203, and more particularly, to cancel disturbance in the non- switched or static mirrors of the MEMS device 203 caused by switched or movi ng mirrors.
