摘要： A modulator for modulating incident rays of light, the modulator comprising a plurality of equally spaced apart beam elements, each of which includes a light reflective planar surface. The elements are arranged parallel to each other with their light reflective surfaces parallel to each other. The modulator includes means for supporting the beam elements in relation to one another and means for moving the beam elements relative to one another so that the beams move between a first configuration wherein the modulator acts to reflect the incident rays of light as a plane mirror, and a second configuration wherein the modulator diffracts the incident rays of light as they are reflected therefrom. At least one of the facing surfaces of the beam elements and underlying substrate is configured to reduce any tendency to stick as they are pulled together. In operation, the light reflective surfaces of the beam elements remain parallel to each other in both the first and the second configurations and the perpendicular spacing between the reflective surfaces of adjacent beam elements is equal to m/4 times the wavelength of the incident rays of light, wherein m=an even whole number or zero when the beam elements are in the first configuration and m=an odd number when the beam elements are in the second configuration.

摘要： Linear phase aberrations in laser amplifier systems are adaptively corrected by a device which propagates an object beam formed by reflection of a laser beam from a target backwards through a laser amplifier chain in order to sample the linear phase aberrations and produces a conjugate image beam by degenerate four-wave mixing in a medium having a third order nonlinearity in susceptibility. The conjugate image beam which is amplified as it propagates back through the laser amplifier chain has the linear phase aberrations removed. The device also corrects for birefringent aberrations contained in the laser amplifier chain when (1) the medium has an isotropic nonlinearity; (2) the polarization of the pump beams, required for four-wave mixing, lies in the plane formed by the object beam and the pump beams; and (3) the angle between the object beams and the pump beams is substantially 90 degrees. The degenerate four-wave mixing is accomplished in one embodiment by gain saturation in Nd:YAG.

摘要： A device for creating microgradients in solution is disclosed. The device contains a microfluidic channel with openings at each end and two or more small apertures to a bath. Electrodes are placed in the openings at either end of the channel and an electrical power supply is connected to the electrodes. Several distinct current paths exist from one end of the channel to the other. For example current may flow from one electrode, through a portion of the channel, through an aperture into the bath, back through another aperture into the channel, and along another portion of the channel to the other electrode. Current flows along all possible connected paths when an electric field is applied along the channel and induces fluid flow into and out of the apertures in the channel. Fluid flow through the apertures results in the formation of microgradients in solution near the microfluidic channel device.

摘要： A phase plate and lens modify light beams emitted by an array of lasers to form an efficient illumination source for a MEMS light modulator array. The phase of the electric field emitted by the lasers is modified such that the after passing through a lens the beam profile at the lens focal plane has an approximately rectangular shape appropriate for illuminating a light modulator array. The phase plate may be constructed from a glass plate with rectangular notches etched in it or with rectangular ridges formed on it. Furthermore a light source, such as a laser, may be coupled to an adiabatically tapered optical waveguide in which a phase adjusting block is introduced in analogy to notches in a bulk phase plate. Phase modified light beams output from the waveguide system have similar focusing properties to those passing through a bulk phase plate.

摘要： Multi-point confocal microscopy, bright field microscope imaging, computer-controlled positioning stages, and an algorithm for automated leveling are the basis for a powerful but simple tool for aligning stamps used in precise pattern transfer to substrates. The system is relatively inexpensive and brings a capability similar to that of a photolithographic mask aligner to the world of elastomeric-stamp-based lithography. Alignment of the stamp and substrate is possible without contact between the two before printing.
