摘要： In a first aspect, a lithography apparatus may comprise a mask designed using optical proximity correction (OPC), a pulsed laser source, and an active bandwidth control system configured to increase the bandwidth of a subsequent pulse in response to a measured pulse bandwidth that is below a predetermined bandwidth range and increase a bandwidth of a subsequent pulse in response to a measured pulse bandwidth that is above the predetermined bandwidth range. In another aspect an active bandwidth control system may include an optic for altering a wavefront of a laser beam in a laser cavity of the laser source to selectively adjust an output laser bandwidth in response to the control signal. In yet another aspect, the bandwidth of a laser having a wavelength variation across an aperture may be actively controlled by an aperture blocking element that is moveable to adjust a size of the aperture.

摘要： A polarimeter with a polarization state generator and a polarization state analyzer mounted together on a single rotary mount. This novel structure allows built-in alignment and synchronization of the polarization state analyzer and the polarization state generator. Because of this built-in alignment and synchronization, polarization properties of samples can be measured quickly, accurately, inexpensively, and reliably. The instrument can measure polarization properties of remote samples, without placing the sample inside the instrument. The surrounding lenses and mirrors are designed in such a way that light leaving the instrument will pass through the polarization state generator and light returning into the instrument will pass through the polarization state analyzer and onto a photodetector. Samples can be measured directly in reflection or in small-angle backscatter; or they can be measured in double-pass transmission with the addition of a mirror or retroreflector.

摘要： A modular three-dimensional (3D) optical switch that is scalable and that provides monitor and control of MEMS mirror arrays. A first switch module includes an array of input channels. Light beams received from the input channels are directed toward a first wavelength selective mirror. The light beams are reflected off of the first wavelength selective mirror and onto a first array of moveable micromirrors. The moveable micromirrors are adjusted so that the light beams reflect therefrom and enter a second switch module where they impinge upon a second array of moveable micromirrors. The light beams reflect off of the second array of moveable micromirrors and impinge upon a second wavelength selective mirror. The light beams reflect off of the second wavelength selective mirror and into an array of output channels. The alignment or misalignment of a data path through the switch is detected by directing two monitor beams through the data path, one in the forward direction and one in the reverse direction. The position of each of the monitor beams is detected after its reflection from the second moveable micromirror that it hits. The position data is used to determine the angles of the moveable micromirrors in the data path.
