Title: Compound semiconductor element
Inventor: YAMADA ATSUSHI
IPC: H01L31/10
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To provide a compound semiconductor element in which light at a specific wavelength contributes largely by a method in which the compound semiconductor element is composed of a compound semiconductor having a region in which a change in the thickness direction in a composition ratio is a parabolic function shape. SOLUTION: For example, in an Alx Ga1-x As system, the composition of a barrier layer Al at both ends of a parabola is set at 0.45, and the composition of the Al in the position of the vortex of the parabola, i.e., at the bottom of a quantum well, is set at x=0. The width of the parabola is formed so as to become 44 ML (a monoatomic layer, 1 ML=0.283nm). At this time, (x) is changed continuously in such a way that a potential shape becomes a parabola. In a quantum well structure whose potential shape is a parabolic function shape, electrons are transited up to a high level while they are emitting light in an avalanche shape from a high-order excitation level down to a base level. At this time, wavelengths of light emitted due to their transition between respective levels are all equal.  As a result, the intensity of the light emitted as a whole can be expressed as the sum of intensities of light emissions due to the transition between the respective levels, and light at a specific wavelength can contribute largely.

Abstract: PURPOSE: To avoid distortion due to quantized error and to enable high performance, by using a DA converter having external reference input terminals as the 1st and 2nd converters and making practically the step size at expanding dense.  
     CONSTITUTION: In the expanding operation of a DA conversion circuit by K bits, when an inputted digital signal has an information area of ≥1/2K full scale, a reference voltage is given from a reference voltage source SV to an external reference input terminal 3 of the 1st DA converter DAC 1 . Simultaneously, the information in K bits including the least significant digit of the input digital signal is inputted to the 2nd DA converter DAC 2  an external reference input terminal 4 of which has the external reference voltage, and a quantized error voltage obtained is used as a correction voltage and it is applied to a terminal 3 of the converter DAC 1 . Thus, the step size which becomes coarse at expansion can be made dense through the correcting voltage.

Title: Variable light frequency light source
Inventor: TACHIKAWA YOSHIHIKO
IPC: G01M11/00
Filed: 1995-01-27
Abstract: PURPOSE: To sweep a light frequency straight by setting a delay means for delaying light, detecting the changing amount of the light frequency per unit time, and controlling the changing amount to be constant by a control means. CONSTITUTION: The light projected from an electrooptic converter (E/O converter) 1 is output outside through an isolator 4 and a beam splitter 5. The light split by the beam splitter 5 passes a beam splitter 6 to enter an optical fiber 7 of a known length. The light projected from the optical fiber 7 enters an optical multiplexer 8, where the light is combined with the light split at the beam splitter 6. The combined light is converted to an electric signal by a photodetector 9. At this time, a signal of a frequency equal to the product of an inclination of a change of a light frequency and a delay time by the optical fiber 7 is output from the photodetector 9. If the inclination of the change of the light frequency is sweeped straight, the signal output from the photodetector 9 has a constant frequency.
