摘要： An opto-electronic semiconductor component having a light transmission or receiving property including a light emitting or detecting active zone lying parallel to the principle surface of the semiconductor crystal is formed so that it detects or emits light directed parallel to the active zone with high efficiency. This enables the component to be hybridize with other electrical, electro-optical or optical elements in a single plane. At least one lateral surface of the semiconductor crystal is inclined at an angle to the principle surface of the component such that light directed into or from the crystal in a direction parallel to the active zone experiences deflection by refraction or reflection toward or away from the active zone.

摘要： An optical coupling element having a convex, refractive microlens is characterized by a ball having a flat, planar surface being mounted in a through-hole of a carrier lamina with the flat, planar surface extending parallel to a planar surface of the lamina. The coupling element is preferably made by a method which involves forming a through-hole in a lamina, mounting a ball in the through-hole, processing a surface of the ball to form the planar surface that extends parallel to a surface of the lamina. Preferably, a plurality of coupling elements are formed by providing a plurality of through-holes in an enlarged carrier and after processing, each individual coupling element is then separated from this enlarged carrier.

摘要： A lensless optical servo system (100) has an unfocused light source (102) and patterned photodetectors (104, 106, 108). The unfocused light is reflected by the markings on an LS-120 disk (40) and the reflected light carries the pattern of the markings the considerable distance in its far-field to the photodetectors (104, 106, 108). The convolution of this light pattern and a mating geometric pattern (110, 112, 114) on the photodetectors (104, 106, 108) causes the photodetectors to generate signals representing the position of the track on the disk. According to a presently preferred embodiment, a laser diode (102) and three detectors (104, 106, 108) are formed on the same silicon substrate (101). Sinusoidal metalization (110, 112, 114) is applied to the detectors (104, 106, 108) in the radial direction. The period of the sinusoidal metalization is two times the tracking pitch of the disk radially and tangentially. The metalization on the first detector is approximately ninety degrees behind the metalization on the second detector and the metalization on the third detector is approximately ninety degrees ahead of the metalization on the second detector. Preferably, each detector (104, 106, 108) is provided with two sinusoidal patterns (110a, 110b, 112a, 112b, 114a, 114), approximately one hundred eighty degrees out of phase with each other, and spaced apart in the tangential direction.

摘要： An optoelectronic transducer includes a base plate, a radiation-emitting or transmitting semiconductor component disposed on the base plate, an optical lens system aimed at the semiconductor component and a spacer joined to the base plate for the lens system. The base plate, the spacer and the lens system are formed of materials with at least similar coefficients of thermal expansion. A method for producing an optoelectronic transducer includes forming indentations in a base plate for receiving semiconductor components, while leaving a land remaining on at least one side of each of the indentations. A first plate of the size of the base plate is placed on the lands and joined to the lands by material locking. The first plate is removed between the lands producing spacers joined to the base plate. A number of the semiconductor components are inserted into the indentations in accordance with a predetermined grid pattern and are joined to the base plate to form substrates. The substrates are covered with a second plate including a number of lens systems correspopnding to number of semiconductor components, while placing the lens systems of the second plate in the same grid pattern. The second plate is adjusted relative to the substrates for aiming each of the lens systems at a respective one of the semiconductor components. The second plate is secured to the substrates.
