Title: Optical semiconductor device and light source
Inventor: TSUBOTA TAKASHI
IPC: H01S5/10
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser which enables reduction in intensity noise. SOLUTION: When a voltage is applied between an n-type InP substrate 1 (-) and a p-type InP clad layer 6 (+), a laser beam generated by the recombination of electrons excited by a voltage applied within an InGaAsP active layer 2 is reflected by an emission end surface 7 and a rear end surface 8 and fed back into the InGaAsP active layer 2, thus causing laser oscillation. Since the reflectance of the emission end surface 7 is set to be higher than the reflectance of the rear end surface 8, a laser beam (returned light) reflected by a optical waveguide or the like is unlikely to be incident on the InGaAsP active layer 2, even when the reflected return light is intended to be incident on the InGaAsP active layer 2.

Filed: 1985-10-26
Abstract: PURPOSE:To permit suction and discharge of fluid with a simple construction, by applying voltage to both piezoelectric ceramic plates fixed to the outer surfaces of both vibration plates, and alternately vibrating the vibration plates in the directions where the opposed surfaces are moved away and approached to increase and decrease a volume in a pump chamber. CONSTITUTION:When an electrode rod is connected to an A.C. power source, and a positive voltage is applied to both piezoelectric ceramic plate 15 fixed to the outer surfaces of both vibration plates 4, both the ceramic plates 15 are radially outwardly distorted, and accordingly both the vibration plates 4 are outwardly expanded and flexed. Conversely, when a negative voltage is applied, both the piezoelectric ceramic plates 15 are radially inwardly distorted, and both the vibration plates 4 are inwardly contracted and flexed. In this manner, the positive and negative voltage is alternately applied to the piezoelectric ceramic plates 15, 15 to thereby alternately flex both the vibration plates 4 in the directions where the opposed surfaces are moved away and approached. As a result, the capacity of a pump 10 may be increased and decreased. Thus, a fluid is sucked from a suction port 12, and is discharged from a discharge port 13 with a simple construction to exhibit the performance of a piezo pump.
