20080247427 | Optical systems for laser arrays - Surface emitting laser arrays with intra-cavity harmonic generation are coupled to an optical system that extracts harmonic light in both directions from an intra-cavity nonlinear optical material in such a way that the focusing properties of the light beams are matched. | 10-09-2008 |
20080273557 | Illumination system for optical modulators - 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. | 11-06-2008 |

20140034498 | Localized Chemical Microgradients - 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. | 02-06-2014 |
