IPC: H01L33/40
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To stabilize a horizontal transverse mode by a method wherein, when a nitride semiconductor layer is etched, an etching method in which an etching speed has Al composition dependence is used, and a second nitride semiconductor layer having a different Al composition from a first nitride semiconductor layer is used as an etching stopper layer. SOLUTION: In a step of manufacturing a GaN system semiconductor laser, a p-type clad layer is formed as a three-layered structure comprising a first p-AlGaN layer 208, a second p-AlGaN 210, and a p-GaN layer 209 are pinched therebetween. Furthermore, by use of an etchant of which the etching rate of GaN is smaller than that of AlGaN, the second p-AlGaN layer 210 is etched. Thus, the etching when forming a ridge strip can be stopped in a p-GaN etching stoppage line. As this result, control of a film thickness left behind in the p- AlGaN clad layer 210 is enhanced, and it becomes possible to stabilize a horizontal and transverse mode.

Title: Automatic detector
Inventor: MATSUSHITA KOJI
IPC: G11B20/10
Filed: 1987-06-04
Abstract: PURPOSE:To automatically follow the change of a transmission line characteristic without using an equalizer by extracting the response waveform of a special pattern and forecasting an input waveform based on the superposition of the response waveform. CONSTITUTION:A discriminator 10 discriminates a digital value from an input value. On the other hand, at a delaying memory 11, a time input side equivalent to the time delay of the discriminator 10 is delayed and the impulse response waveform is removed by a waveform extracting device 12. A response waveform correcting device 13 corrects the transmission line impulse response value string based on the output of the waveform extracting equipment 12. These impulse response value strings are given to the discriminator 10. Thus, since as the superposition of the response waveform, the input waveform of the discriminator 10 is forecast, the most definite discriminating value is discriminated, the response waveform of the special pattern is always measured and updated, the detector can follow the change of the transmission line characteristic.

CONSTITUTION:A light source 2 is oscillated at a frequency nucw, and the light is emitted into (a) of an optical switch 9. The light is transmitted through an optical fiber 7. At the time when the light reaches the entire length of the fiber 7, the switch is changed to (b), and the light of the light source 2 is applied. At this time the oscillating frequency is made to be nup at the same time. For the frequency nup at this time, the difference DELTAnu is made to agree with a Brillouin frequency nub of the fiber 7. Thereafter, the light becomes the pulse light with an optical pulse generator 3. The light is transmitted through the fiber 7. At this time, the light of nucw undergoes Brillouin optical amplification in the optical fiber 7 by the light/electric-power conversion step from the light of the frequency nup to the light of the frequency nucw until the time when the pulse light reaches the position that is the half point of the fiber 7. The distortion distribution can be measured by analyzing the light.
