    摘要: The present invention discloses a multiple-beam holographic optical pick-up head, which has the advantages of the multiple-beam optical pick-up head and the holographic optical pick-up head and can increase the light usage efficiency. This invention uses the property that a polarized diffractive optical element can generate different optical effects for laser beam with different polarizations and places a polarized multiple-beam grating and polarized hologram on the optical path for splitting the incident light toward the disc into multiple reading beams by the multiple-beam grating. The returning laser beams reflected from the disc are diffracted and diverted by the hologram to reach a photodetector. Both the incident and reflective beams are diffracted once only; thus the light usage efficiency can be increased.

    摘要: The invention is directed to a sieving apparatus for a bio-chip, which has a light source, a HOE unit, a splitter, an objective lens, a filter, and an optical signal sensor. The HOE unit is coupled with a light source, so as to diffract the light into a zeroth order beam and a first order beam. The zeroth order beam has no deflection but the first order beam has a deflection from the zeroth order beam. The splitter is coupled to the HOE unit, so as to lead the two beams to the objective lens, which further leads the two beams to the bio-chip, in which the first order beam is incident onto the bio-chip from an incident angle, causing a florescent light from the sample. The bio-chip also reflects the zeroth order beam. Both the reflected zeroth order beam and the fluorescent light travel through the objective lens and the splitter. The filter is coupled to the splitter, so that an undesired portion of the light beams incident on the splitter is filtered. The optical sensor receives the light beams after the filter. The zeroth order beam is used to generate a focusing signal and a tracking signal. The focussing signal and the tracking signal are used to control the servo, so as to align the optical sensor to the samples for detecting the florescent light. Alternatively, the sensor can be fixed but the bio-chip is shifted by the servo system.

    摘要: A spin transistor and a manufacturing method thereof are provided. The method includes defining a required area on a substrate by lithography; forming a doping area by ion-implantation, and forming a magnetoresistive film on the substrate. Finally, the method produces a spin transistor with the emitter, the base, and the collector in the same plane surface. The manufacturing method integrates the emitter, the base, and the collector into one plane, so that miniaturization of the spin transistor is achieved, and it is advantageous for the integration and subsequent packaging of the spin transistor and integrated circuit elements.

    摘要: A magneto-resistance transistor including a magneto-resistant element which may function as an emitter and a passive element which may function as a collector. The base may be interposed between the passive element and the magneto-resistant element, thereby coupling the passive element with the magneto-resistant element. A magnetic field of a given strength may be applied to at least a portion of the magneto-resistant transistor, the given strength determining a resistance in the at least a portion of the magneto-resistant transistor. Thus, by adjusting the given strength of the magnetic field, the resistance may be adjusted. Therefore, different emitter current inputs may be achieved with a fixed voltage. Further, a base current may vary with a controlled variation of the emitter current input.
