Title: Quantum well laser
Inventor: SUGIMOTO MITSUNORI
IPC: H01S5/00
Filed: 1985-06-24
Abstract: PURPOSE:To improve an efficiency of injection of carriers of electrons into a quantum well and thereby to make a quantum well laser excellent in characteristics by a construction which enables the establishment of a specific formula when the lowest energy level of a bound energy level is E1 and when an energy at the lower end of an electron conduction band of a containment layer of the quantum well on the N side is EC2. CONSTITUTION:Electrons of a continuous level of a quantum well 3 and a first guide layer 2 are thought to be distributed according to Fermi distribution. In this distribution, the number of electrons increases as an energy lowers, and this number turns to be maximum in the vicinity of the lower end of a conduction band of the first guide layer 2. When the lowset level E1 of a dummy bound level is present in the vicinity of an energy EC2 at the lower end of the conduction band of the first guide layer 2, accordingly, both the distribution and the probability of existence are maximum, and therefore the number of electrons at the continuous level of the quantum well 3 are maximum. The condition wherein said number is maximum is expressed by EC2<=E1<=EC2+0.05eV. By adopting an appropriate value for the energy EC2 so that E1 meets the formula, efficient injection of electrons into the quantum well 3 can be performed.

A frequency/voltage setting device 4 sets an inverter frequency command (IF)F and an output power command E. A gate signal generating device 3 generates a gate signal of the inverter primary circuit element according to the SFF and IFF and the output power command E. Therefore, at the other operation modes than the normal operation mode, loss of a switching element is held down to such a degree that the loss at the other operation modes may not exceed a loss at the normal operation mode. As a result, the size of a cooling equipment of the element is not required to be enlarged and a high-efficiency and small-size equipment can be materialized.
