Methods and apparatus for depositing a high density biological or chemical array onto a solid support. Specifically, the apparatus is made up of a plurality of open ended channels collectively forming a matrix. The matrix has been redrawn and cut such that the pitch of the channels on the loading end is larger than the pitch of the channels on the liquid delivery end. The upper portion of each channel serves as a reservoir, while the opposing end, which has been formed by the redrawing process, is diametrically sized such that liquid in the reservoir is retained by capillary pressure at the delivery end. At any point along the height of the capillary reservoir device, all cross-sectional dimensions and areas are uniformly reduced. In other words, the on-center orientation of any two channels, also referred to as the pitch between 2 channels, measured as a function of the diameter of any cross section, is constant throughout the structure. The liquid within the channels is either printed directly from the tool onto a substrate or transferred to a substrate by a typographical pin plate. In another embodiment, the device may be used in transferring sample between multiwell plates of different well density.

Active photonic crystal devices for controlling an optical signal is disclosed. The devices include a planar photonic crystal with a defect waveguide. In one embodiment of the invention, the propagation of the optical signal is controlled by changing a dimension of the planar photonic crystal structure. In another embodiment, the propagation of the optical signal is controlled by inserting rods into the columnar holes of the planar photonic crystal structure. In a third embodiment of the invention, the propagation of the optical signal is controlled by filling the holes of the planar photonic crystal structure with fluid.

Active photonic crystal waveguide device

A micro-electro-mechanical system (MEMS) optical switch has a passive latching system. The switch includes a reflective element and a switch actuator for moving the reflective element to a first position based on a switching signal. The passive latching system is coupled to the switch actuator, where the passive latching system maintains the reflective element in the first position when the switching signal is discontinued. The latching system has a first magnet configuration coupled to a first portion of the switch actuator, and a second magnet configuration coupled to a second portion of the actuator. Thus, a magnetic force biases the magnetic configurations together when the reflective element is in the first position and the switching signal is discontinued. The latching is discontinued by using the switching signal to raise the temperature of one of the magnet configurations above its Curie point. The use of a passive latching system improves reliability, reduces cost, and enables the optical switch to serve as a viable alternative to conventional switching devices.

A fluid encapsulated MEMS optical switch includes an optical waveguide matrix with MEMS mirrors situated in trenches located at waveguide cross-points. The trenches are filled with collimation-maintaining fluid and the mirrors are immersed therein. The collimation maintaining fluid prevents the light beam from spreading when it enters the switch cross-points. This feature enables the use of much smaller MEMS mirrors and prevents some of the typical MEMS mirror problems found in the related art. In particular, the MEMS mirror disclosed in the present invention is reduced to approximately 15 &mgr;m wide and 2 &mgr;m thick, resulting in shorter actuation distances of approximately 15 &mgr;m. This feature results in an optical switch having faster switching times.

A method of printing electrode and electronic circuit patterns. A metal frit containing part is transferred from an intaglio recessed imaging pattern to a suitable substrate. The frit pattern is preferrably cured during deposition to the substrate.

Method of making an electronic printed structure

A method for making color filters for liquid crystal display panels. A raised pattern corresponding to the desired black matrix pattern is formed on a substrate, e.g., by an embossing means. A plurality of colored ink patterns is formed in the appropriate location within the boundaries formed by the raised pattern, thereby forming the multicolor image that will become the color filter.

A method and apparatus for making formed glass structures. A glass frit containing material is deposited within a recessed pattern, hardened in the recessed pattern, and transferred to a substrate. The method and apparatus of the invention are particularly useful for forming barrier rib structures for use in plasma display panels.

The panel has substrate (4) which has a network of barriers each incorporating electrode (6.sub.i) of a first network of electrodes for control of the panel, a periodic arrangement (R.sub.i, V.sub.i, B.sub.i) of areas of phosphorescent products being formed on substrate (4), transparent front plate (8), second network of electrodes (10.sub.j) perpendicular to electrodes (6.sub.i), an ionizable gas which is introduced between this substrate and this plate. In order to manufacture substrate (4), one forms a metallic plate which has joined preforms of electrodes (6.sub.i) of the first network, one covers the preforms with a layer of a dielectric material which is molded on it them and on the spaces separating them, and one removes the material from the metallic plate which joins the preforms of electrodes (6.sub.i), so as to electrically insulate these electrodes from one another.

A method and apparatus for making color filters for liquid crystal display panels. A transfer layer is formed on a collector roll, and a raised pattern corresponding to the desired black matrix pattern is formed on the transfer layer by an embossing means. A plurality of colored ink patterns is formed in the appropriate location within the boundaries formed by the raised pattern, thereby forming the multicolor image that will become the color filter. This multicolored image is then transferred to the substrate. Preferably, the inks are deposited into the black matrix pattern using typographic imaging pins which are smaller than the cells of the black matrix pattern.
