摘要： A method for non-active processing of an etched surface in a vertical-cavity surface-emitting laser diode is provided. In order to obtain a stable single fundamental transverse mode, at a low temperature of 100 to 300 degrees, an amorphous GaAs is deposited on a surface of an etched active layer and an etched cavity. Also, a bottom emitting laser is provided which is formed by, with the metal electrode as a mask, etching the top mirror layer and the active layer, depositing the amorphous GaAs onto the etched portion and planarizing the deposited GaAs layer and depositing p-type metal pad over the amorphous GaAs around the formed laser device. Also, a top emission type laser is provided which is formed by, with a photoresist as a mask, etching the top mirror layer and the active layer, planarizing the GaAs layer and depositing p-type metal pad containing a window for light emission which is made smaller than laser area over the amorphous GaAs around the formed laser device. Thus, a more stable single fundamental transverse mode than in the conventional device can be obtained.

摘要： 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.

摘要： Disclosed is an operation principle and an epitaxial structure of resonant tunneling opto-electronic device. According to the present invention, the photo-generated holes stored in front of the double barrier quantum well structure by light illumination. As a result, a large potential drop occurs in the double barrier quantum well structure. And a peak signal of the opto-electronic resonant tunneling device is generated at a relatively lower voltage illumination to one generated before introducing the light into the device. An amount of photocurrent is 10.sup.3 times and over as compared to the conventional p-i-n diode because a resonant tunneling current is optically controlled by light illumination. So that, it is possible to drive peripheral circuit without use of additional amplifiers for amplifying an output signal from the opto-electronic device.
