摘要： A focusing and tracking method and system for use on the read/write head of an optical drive is provided. The focusing and tracking method and system is capable of detecting both the focusing error and the tracking error of the read/write head to thereby control the focusing and tracking of the same during read operation. In particular, this focusing and tracking method and system combines the use of a knife-edge focusing method and a push-pull tracking method respectively for focusing and tracking of the read/write head. A specially designed photo detector is used to obtain both the focusing error signal and the tracking error signal. This allows the focusing and tracking system to be simplified in structural complexity, thereby saving manufacturing cost. Moreover, since the focusing error signal and the tracking error signal are obtained respectively in perpendicular directions, the undesired effect of cross-talk between the two error signals can be avoided.

摘要： A method for measuring a surface structure of a near-field object is provided. A light source produces at least a first light beam and a second light beam; guiding the first light beam and the second light beam to enter the SIL for interacting with the object surface. This method can be used in, for example, a near-field optical disc storage system, wherein reflection intensities of the first and second light beams are used to measure two distances between the SIL and the optical disc at two positions corresponding to the first and second light beams. A surface structure, such as a tilt angle or an average distance between the disc and the SIL or disc roughness, is obtained by analyzing the above-mentioned positions and distances. The first and second light beams are produced, for example, by a diffraction technology or by a single laser diode with multiple beams.

摘要： A planar integrated micro-optical pickup head is used to perform reading and writing operations on a high-density disk. The planar integrated micro-optical pickup head includes a set of optical elements that is comprised of a beam splitter, a plurality of 45-degrees-oriented folding mirrors, and two planar collimators. The pickup head further comprises a photo-detector, a laser source for emitting a laser beam of short wavelength, and an objective lens of high value of numerical aperture. The set of optical elements is formed on lower and upper substrates via semiconductor planar fabrication processes, the laser source and the objective lens then are mechanically attached on the lower substrate. The lower and upper substrates are ultimately aligned and attached with each other to achieve the pickup head hence having a reduced size and simply fabricated.

摘要： A method of manufacturing a two-color filter. The method includes forming a first metallic layer over a substrate and then forming a second metallic layer over the first metallic layer. A patterned photoresist layer is formed over the second metallic layer. A portion of the first metallic layer and the second metallic layer in region not covered by the photoresist layer are removed by etching to form a third metallic layer and a fourth metallic layer over the substrate respectively. An optical film is formed over the photoresist layer and the substrate such that the optical film is able to cover only a portion of the sidewalls of the fourth metallic layer or a portion of the third metallic layer. The extent of coverage by the optical film on the sidewalls can be controlled through careful adjustment of the thickness of the first and the second metallic layer. Finally, the third metallic layer, the fourth metallic layer and the photoresist layer are removed so that an optical film previously attached to the sidewalls of the third and fourth metallic layer remains over the substrate.

摘要： A two-wavelength laser pick-up head used for accessing DVD, CD, CD-R and CD-E systems. The two-wavelength laser pick-up head includes a shorter wavelength laser optical path for reading the data from a DVD system, and a longer wavelength laser optical path for reading the data from a CD or CD-R system. The above two optical paths use the same collimator and the same objective lens. There is a compensator lens which is used in the longer wavelength laser optical path for correcting the spherical aberration due to the thick substrate of the CD or CD-R.

摘要： A beam shaper device for an optical read/write head on an optical disc drive is provided. This beam shaper device is particularly useful for shaping a laser beam originally emitted with an elliptical cross section, into having a substantially circular cross section. The beam shaper device includes only one prism and one plane mirror. The shape of the prism and the orientation of the plane mirror are specifically devised in such a way as to allow the output beam shaper device to have a circular cross section and to have its propagation axis orthogonal to that of the input laser beam.
