    摘要： An optical assembly includes a waveguide assembly and an optical coupling element. The waveguide assembly includes a core, a cladding portion, and, preferably, at least two waveguide core fiducials, the at least two waveguide core fiducials and the core being lithographically formed substantially simultaneously in a substantially coplanar layer The core and the at least two waveguide core fiducials are formed in a predetermined relationship with the cladding portion. The optical coupling element (for example, a lens array or mechanical transfer (MT) ferrule), includes an optical element and, preferably, at least two alignment features associated with the optical element, the at least two alignment features being mated with the at least two waveguide cote fiducials to accurately position the optical element with respect to the core in an X-Y plane A method of alignment is also provided

    摘要： A multiple laser beam scanning optical system for correcting monochromatic and polychromatic aberrations comprising a doublet cylindrical lens for receiving the multiple beams and directing them to a rotating polygonal mirror. Scanning lens means are located to receive the beams from the mirror and direct them to the image plane. The scanning lens is comprised of at least one doublet wherein both elements have approximately the same index of refraction but different dispersion factors at a nominal wavelength

    摘要： Error correction in a feedback servo system. The feedback servo loop in, for example, a head positioning circuit in an optical disk data recording and retrieval system is provided with means for forcing the feedback signal to zero when the head is positioned at best focus as determined by a peak in the laser monitoring diode. The head in such a system must be dynamically maintained at a best focus position but, through use and transporting, the alignment of the head position error detecting system can be disturbed. In some cases, the loop circuit parameters may drift from their original values. To correct for errors introduced from such causes, the head is positioned at best focus and the focus error (head position error) signal is sensed. A correction system forces the sensed value to zero, e.g, by adjusting the gain of amplifiers used in the feedback loop.

    摘要： Method of fabricating a semiconductor die with a microlens associated therewith. More particularly, a method for fabricating a vertical channel guide optical via through a silicon substrate wherein the optical via can contain lens elements, a discrete index gradient guiding pillar and other embodiments. Also disclosed are means for transferring, coupling and or focusing light from an electronic-optical device on the top of a semiconductor substrate through the substrate to a waveguiding medium below the substrate. The high alignment accuracies afforded by standard semiconductor fabrication processes are exploited so as to obviate the need for active alignment of the optical coupling or light guiding elements.
