摘要： An avalanche-type detector circuit includes an avalanche-type photon detector device, a coupling capacitor, a bias network, a first transmission line and a second transmission line. The coupling capacitor has a first terminal that is coupled to a first terminal of the avalanche-type photon detector device. A first terminal of the bias network is coupled to the first terminal of the avalanche-type photon detector device, while a second terminal of the bias network is coupled to a bias voltage so that the avalanche-type photon detector device is reverse biased. A first end of the first transmission line is coupled to a second terminal of the coupling capacitor, and second end of the first transmission line is terminated by an open-circuit termination. A first end of the second transmission line is coupled to a second terminal of the avalanche-type photon detector device. The second end of the second transmission line is terminated by a short-circuit termination. A bias pulse voltage Vpulse is coupled to the second terminal of the coupling capacitor such that the bias pulse voltage reverse biases the avalanche-type photon detector device to be greater than a reverse breakdown voltage Vbr of the avalanche-type photon detector device during a duration of the bias pulse voltage Vpulse. A round-trip propagation delay along the first transmission line is substantially equal to a round-trip propagation delay along the second transmission line.

摘要： Disclosed herein is a method of forming polymer structures comprising applying a solution of a diblock copolymer assembly comprising at least one diblock copolymer that forms lamellae, to a neutral surface of a substrate having a chemical pattern thereon, the chemical pattern comprising alternating pinning and neutral regions that are chemically distinct and which have a chemical pattern spatial frequency given by the number of paired sets of pinning and neutral regions along a given direction on the substrate; and forming domains comprising blocks of the diblock copolymer. The domains form by lateral segregation of the blocks. At least one domain has an affinity for the pinning regions and forms on the pinning region, the domains so formed on the pinning region are aligned with the underlying chemical pattern, and domains that do not form on the pinning region form adjacent to and are aligned with the domains formed on the pinning regions. In this way, a structure comprising repeating sets of domains is formed on the chemical pattern with a spatial frequency given by the number of repeating sets of domains in the given direction, that is at least twice that of the chemical pattern spatial frequency. Methods of forming the chemical patterns, and pattern transfer methods using patterned domains, are also disclosed.

In one method, a pre-patterned structure is provided which comprises i) a support member having a surface and ii) an element for topographically guiding segregation of a polymer mixture including a first polymer and a second polymer, the element comprising a feature having a sidewall adjoined to the surface. The polymer mixture is disposed on the pre-patterned structure, wherein the disposed polymer mixture has contact with the sidewall and the surface. The first polymer and the second polymer are segregated in a plane parallel to the surface, thereby forming a segregated structure comprising a first polymer domain and a second polymer domain. The first polymer domain and/or the second polymer domain are lithographically patterned, thereby forming topographical features comprising at least one of i) a first feature comprising a lithographically patterned first polymer domain and ii) a second feature comprising a lithographically patterned second polymer domain.

摘要： Electromagnetic radiation from an optical source is directed onto a metallic structure. The metallic structure in turn emits optical output from an emission region in the structure and onto a recording medium (e.g., a magnetic recording disk), thereby heating the medium. The output from the emission region is enhanced due to surface plasmons in the metallic structure. The surface plasmons are generated by an array of features (such as ridges or trenches) in the metallic structure and act to increase the emitted optical output from the emission region beyond what the emitted optical output from the emission region would be in the absence of these features. The apparatus and associated method are useful for data recording, e.g., thermally assisted data recording.

摘要： A magnetic recording disk drive with patterned disk media, wherein discrete magnetic data blocks representative of the individual data bits are isolated from one another, uses the discrete data blocks as the source of the clocking signal to the write head. The carrier for the read/write head includes a special pattern sensor that senses the data blocks in the data tracks before they pass beneath the write head. The pattern sensor output serves as the clocking signal to precisely control the placement of the write pulses by the write head. A time delay is calculated using a timing mark on the patterned disk to delay the write pulses so that a data block sensed by the pattern sensor is the same data block to which the write pulse is applied. In this manner the actual previously recorded data provides the synchronization or clocking signal to control the writing of the new data. The time delay is calculated from measurement of the time for a timing mark to pass from the pattern sensor to the read head and from known spacings of the pattern sensor, read head and write head on the head carrier.
