摘要： Methods, devices, and systems for ultrashort pulse laser processing of optically transparent materials are presented, with example applications in scribing, marking, welding, and joining. For example, ultrashort laser pulses create multiple scribe features with one pass of the laser beam across the material, with at least one of the scribe features being formed below the surface of the material. Slightly modifying the ultrashort pulse laser processing conditions produces different types of sub-surface marks. When properly arranged, these marks are clearly visible with correctly aligned illumination through either light scattering or light reflection and nearly invisible without illumination. Transparent material other than glass may be utilized. A method for welding transparent materials uses ultrashort laser pulses to create a bond through localized heating. In some embodiments of transparent material processing, a multifocus beam generator simultaneously forms multiple beam waists spaced depthwise relative to the transparent material, thereby increasing processing speed.

摘要： A non-metallic material is separated using a single laser beam that is converted into a scribe beam and a break beam. A system includes a single laser source for generating a laser beam and a beam separator for converting the laser beam into a scribe beam having a first average power and a break beam having second average power. The beam separator directs the scribe beam to a scribe line on a substrate and the break beam to the substrate at a location that is spaced apart from the scribe beam. The scribe beam rapidly heats the substrate along the scribe line. A quenching subsystem applies a stream of cooling fluid to the substrate to propagate a microcrack along the scribe line. The break beam rapidly reheats the substrate quenched by the stream of cooling fluid to separate the substrate along the microcrack.

摘要： A stream of information is communicated by means of transmission distributed over a plurality of transmission antennas and reception distributed over a plurality of reception antennas. In the method the stream is encoded according to an error correcting code, into a series of multi-bit symbols. A sequence of the multi-bit symbols is interleaved, by which symbols are assigned to time slots, so that the multiple bits of the symbols remain together in the same time slot. The interleaved multi-bit symbols are transmitted, with each symbol distributed over the transmission antennas in a respective time slot. Signals received at the reception antennas in each respective time slot are received and demodulated, to produce demodulation results each for a respective time slot. A time-slot sequence of the demodulation results is deinterleaved. Decoded symbol values are selected under a constraint that a series of the selected symbols belongs to the error correcting code. The selection is performed based on information about the probability of the symbol values, obtained as a function of the demodulation results. A function is used that accounts for correlation effects between the signals from combinations of the reception antennas in a time slot.

摘要： The present invention provides a direct laser writing fabrication method and system for devices having periodic refractive index modulation structures, for example, Bragg gratings. By focusing a modulated pulsed laser beam into a transparent material substrate, a path of laser modified volumes can be formed with modified refractive index compared with the unprocessed material. Modulation of exposure conditions provides periodic or modified periodic waveguide structures such that the waveguide structures exhibit grating responses and can be used for a variety of optical applications, for example, as spectral filters, Bragg reflectors, grating couplers, grating sensors, or other devices. The method enables direct one-step fabrication and integration of periodic or modified periodic refractive-index modulation devices together with other optical waveguiding devices to enable low-cost, multifunctional one-dimensional, two-dimensional or three-dimensional optical circuit fabrication of simple and complex optical systems.

摘要： Disclosed is a radio communications network (RCN) and a method of allocating a resource in a RCN that is configured to provide to a user device at least a first service type and a second service type in a cell of the radio network. A request for a service requiring the resource is received, and the total number of service requests (actual or predicted) is obtained. It is then determined whether the request is for a service of the first type or the second type. If for the first service type, the resource is allocated to the user only if the total number of requests complies with a first threshold specific for the first service type. If for the second service type, the resource is allocated to the user device only if the total number of requests complies with a second threshold being specific for the second service type.
