Title: Semiconductor optical switch
Inventor: KOGA YUJI
IPC: G02F1/313
Filed: 1989-09-01
Abstract: PURPOSE:To increase the degree of freedom of a design of the element by eliminating the upper clad layer between two pieces of adjacent optical waveguides of a directional coupler and forming a dielectric layer being a high resistance electrically in its part. CONSTITUTION:On a semiconductor substrate 4, a layer structure formed by laminating successively a semiconductor lower clad layer 3 of the same conductive type as the substrate, an undope semiconductor waveguide layer 2, a semiconductor upper clad layer 7 of a reverse conductive type to the substrate and a semiconductor cap layer 6 of a reverse conductive type to the substrate is provided, the semiconductor cap layer 6 and the semiconductor upper clad layer 7 are eliminated until reaching the undope semiconductor waveguide layer 2, two pieces of adjacent rib type optical waveguides are formed, and the eliminated semiconductor upper clad layer parts between two pieces of rib type optical waveguides is embedded by a dielectric. In this case, since two pieces of optical waveguides are independent electrically, even if a voltage is applied to one electrode, its influence is not exerted on others, and it is unnecessary that the other electrode is short-circuited to the electrode of the substrate side. In such a way, a low voltage of the element, low power consumption, and also, a high speed can be realized.

Filed: 1995-09-05
Abstract: PROBLEM TO BE SOLVED: To detect the location on the display device tube surface of a detector by determining a maximum measured value from the measured value obtained by the detector and determining the location of the detector for a small area from the maximum measured value. SOLUTION: A detector 3 is mounted on a monitor tube surface 2, the light emitting state and the state of the color of a monitor 1 are measured and the data for proofreading the monitor 1 is obtained. A linear scanning is performed for the small area which is preliminarily fixed on the monitor tube surface 2 and a point scanning is also performed. Therefore, the picture element of the small area emits light for every picture element (or several picture elements) and the remaining parts do not emit light. Next, the measured value by the detector 3 is fetched into a CPU 7. The fetched detection value and the highest measured value so far are compared. As a result of the comarison, when the measured value is larger than the highest measured value so far, the light emitting location and the measured value are recorded.  The obtained highest detection value is defined as the maximum detection value and the light emitting location corresponding to this value is finally recognized as the mounting location of the detector 3.
