An optical signal processor includes a first sub-wavelength grating having a first grating period and a second sub-wavelength grating having a second grating period that is different than the first grating period of the first sub-wavelength grating.

Twin sub-wavelength grating optical signal processor

The present invention provides an improved electrostatic micro actuator array system comprising a plurality of electrostatic micro actuators, each of the micro actuators further comprising at least one hold-down electrode and at least two pull-down electrodes positioned to actuate the micro actuator. A hold-down signal line is then coupled to each of the hold-down electrodes of each of the plurality of micro actuators and a plurality of first pull-down signal lines coupled to one of the at least two pull-down electrodes of each micro actuator and a plurality of second pull-down signal lines coupled to another of the at least two pull-down electrodes of each micro actuator, the first pull-down signal lines and the second pull-down signal lines configured in a cross-point matrix such that a unique pair of first pull-down signal lines and second pull-down signal lines is associated with each of the plurality of micro actuators.

Electrostatically-addressed MEMS array system and method of use

The present invention provides a DC high voltage converter having an oscillator driver, main switch array and topological enhanced capacitors. The switch array utilizes MEM cantilevers and topological capacitors for charge storages for the generation of a high voltage output from a low voltage input.

MEMS DC to DC switching converter

The present invention provides an improved electrostatic micro actuator array system comprising a plurality of electrostatic micro actuators, each of the micro actuators further comprising at least one hold-down electrode and at least two pull-down electrodes positioned to actuate the micro actuator. A hold-down signal line is then coupled to each of the hold-down electrodes of each of the plurality of micro actuators and a plurality of first pull-down signal lines coupled to one of the at least two pull-down electrodes of each micro actuator and a plurality of second pull-down signal lines coupled to another of the at least two pull-down electrodes of each micro actuator, the first pull-down signal lines and the second pull-down signal lines configured in a cross-point matrix such that a unique pair of first pull-down signal lines and second pull-down signal lines is associated with each of the plurality of micro actuators. The system and method of the present invention reduces the number of driving lines required for the micro actuator array. In a particular embodiment, a reconfigurable microelectromechanical (MEMS) micromirror array system capable of deflecting incident light onto or away from a detector is described.

The present invention includes a novel method to fabricate corner cube retroreflectors, CCRs, where a majority of the wafer area acts as CCRs as compared to a maximum of 33% in previous MEMS CCRs. The present invention also allows for the fabrication of moveable cantilevers which operate at one-third the voltage as compared to a conventional planar cantilever.
