The present invention provides cells which are capable of transmitting both optical information and electrical signals when connected with each other, and a packaging system in which these cells are connected. A first connector and a second connector are formed on each cell. These two connectors are configured complementary to each other. When two cells are pressed against each other with the first connector of one of the cells facing the second connector of the other, electrical connectors engage with each other, whereby the cells are connected electrically and mechanically. A first optical device and a second optical device are also disposed in complementary positions. When the cells are connected electrically and mechanically, the tip of the first optical device and the tip of the second optical device are brought into contact with each other, allowing an optical signal to be transmitted.

The present invention relates to optimizing optical power from a laser processing system, and more specifically to a method of optimizing the optical power by employing parallel laser processing techniques to maximize fabrication quality and yield. The method in the present invention includes the steps of: determining the specification for the final product, selecting the proper combination of optical power and processing method for processing a single feature, determining the maximum number of features in pattern to be parallel processed, selecting a portion of the desired pattern that can be parallel processed, designing the DOEs, manufacturing the DOEs, incorporating the DOE into laser processing system, operating and controlling the laser processing system, and determining if more DOEs are needed to complete the laser processing.

A microcavity forming device is provided for making microcavities in a tungsten wire. The microcavity forming device includes a source of particles; a housing for receiving a heated tungsten wire; and a plurality of jet nozzles disposed in the housing for spraying the particles toward the heated tungsten wire. The particles are 0.35&#x2013;0.75 micron in diameter. The heated tungsten wire is received in the housing and the jet nozzles spray the particles toward the tungsten wire to form the microcavities in the tungsten wire.

A photonic crystal comprising a waveguide made of material. The waveguide has a periodic set of holes. The material proximate to at least one of the holes in the periodic set of holes exhibits an index of refraction that has been modified by the application of laser energy relative to the material proximate to other holes in the periodic set of holes.

Method of adjusting the index of refraction of photonic crystals with laser micromachining to tune transmissions within the bandgap and structure

A photonic crystal comprising a waveguide made of material. The waveguide has a periodic set of holes. The material proximate to at least one of the holes in the periodic set of holes exhibits an index of refraction that has been modified by the application of laser energy relative to the material proximate to other holes in the periodic set of holes. The photonic crystal is tuned to temporarily transmit a specific wavelength of light to create an on-off switch for the specific wavelength. Multiple photonic crystals are used to form a multiplexer and a demultiplexer.

A microchannel forming device is provided for making microchannels in a wire. The microchannel forming device includes a plurality of dice for receiving a heated wire spaced along a longitudinal axis. Each die has a circumferential surface forming an opening, and teeth projecting normally from the surface and terminating in the opening. As the heated wire is drawn through the opening of each die, the teeth engage the heated wire to form longitudinal microchannels therein.

A tuned optical resonator having a substrate and an input waveguide and an optical resonator waveguide formed on the substrate. The optical resonator waveguide has a resonant frequency, exhibits a first index of refraction, temporarily exhibits a second index of refraction responsive to application of laser energy, and temporarily resonates at the resonant frequency while the laser energy is being applied.
