Title: Manufacture of strained semiconductor crystal and manufacture of semiconductor laser using it
Inventor: FUJII HIROAKI
IPC: H01S5/00
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To remarkably improve the performance of a semiconductor laser by improving the characteristics, such as the threshold, output, high-speed modulation, etc., of the laser by manufacturing a strongly strained MQW (quantum well) active layer having a thickness which is close to a theoretical critical film thickness. SOLUTION: A strained semiconductor crystal is formed by growing the crystal by using surfactant atoms having an atomic radius which is sufficiently larger than that of the atoms constituting the crystal. The surfactant atoms change the surface energy of the crystal while the crystal is grown and increases the diffusing length of a growing seed. Therefore, a strongly strained MQW active layer 110 which is free from strain releasing can be manufactured by preventing the introduction of point defects to the crystal. Since the surfactant atoms are sufficiently large, the atoms are not taken into the crystal and a high-quality strained semiconductor crystal can be obtained. Therefore, a semiconductor layer having highly reliable characteristics can be realized.

Filed: 1991-11-08
Abstract: PURPOSE:To prevent a pulse width of a line signal from being made narrow by employing a diode biased forward as a generating element of a control voltage controlling a transistor(TR) interposed between choke terminals. CONSTITUTION:A TR interposed between choke terminals is operated in an active region with respect to a DC and even when an AC signal is superimposed onto the DC, the TR is controlled so as not to give effect onto a collector current of the TR.
