Abstract: An improved parallel optical logic operator provides a path for light to pass through substrates in which a light source and an optical logic device are arranged. An optical logic device operates by transmission of light forwarded to a predetermined direction. This increases integration efficiency of the system by eliminating optical parts for changing the light path. A unit chip includes a laser array for generating a predetermined light in accordance with an electrical signal for a logic process, a laser array substrate on which via holes are formed for passing light, a microlens array for converting the light beam emitted from each laser device of the laser array into a parallel light beam for passing through the via hole, and an optical logic circuit array formed with a combination of an S-SEED which performs a logic function by transmission of the light signal through an optical window in S-SEED. A plurality of unit chips are laminated so that the light emitted from the laser device of one of the unit chips passes through an optical logic circuit of a corresponding unit chip and can be made incident on the optical logic circuit in the next unit chip through a via hole.

Abstract: The present invention is a vertical resonant surface-emitting laser, and more particularly, a method for making a micro-laser that can be emitted to the upper surface of resonance structures by forming electrodes on the side surface of the resonance structures. By forming the electrodes injecting the current to the active layer on the side surface of resonators, the electrodes may be formed more easily on the fine micro-laser. Moreover, the current is more efficiently injected to the inside the active layer due to the side electrode surrounding an upper glass layer and emitter, and the laser may be operated even with a smaller start current, and serial resistance of the resonators may be reduced.
