    • 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.

    • 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.
    • 提供了一种在垂直腔表面发射激光二极管中非侵蚀性处理蚀刻表面的方法。 为了获得稳定的单个基本横模,在100至300度的低温下,非晶GaAs沉积在蚀刻的有源层和蚀刻腔的表面上。 另外,提供了以金属电极为掩模形成的底部发射激光器,蚀刻上镜面层和有源层,将非晶GaAs沉积到蚀刻部分上并使沉积的GaAs层平坦化并沉积p型 在形成的激光器件周围的非晶GaAs上的金属焊盘。 另外,提供了以光致抗蚀剂为掩模形成的顶部发射型激光器,蚀刻上镜面层和有源层,使GaAs层平坦化并沉积含有用于发光的窗口的p型金属焊盘, 在形成的激光器件周围的非晶GaAs周围比激光区域小。 因此,可以获得比常规装置更稳定的单根横向模式。
