Title: Optical recording and reproducing device
Inventor: NIMATA AKIO
IPC: G11B7/125
Filed: 1985-02-22
Abstract: PURPOSE:To deal with even the low output area of output characteristics of a semiconductor laser which has polygonal characteristics by switching and controlling of the by-pass current of a semiconductor laser driving circuit. CONSTITUTION:When the output current Io of a light quantity detector 3 corresponding to a polygonal point becomes equal to the total output current Ipd of the light quantity detector 3, a converted voltage generated by a resistance 7 is applied to an input of a comparing circuit 8 at any time so that it attains to a threshold value Ew. Therefore, when the output of the comparing circuit 8 is '0' while the converted voltage of the resistance 7 is below the threshold value Ew, a multiplexer 93 is triggered with the signal '0' and switched to the side of a low-current attenuator 91. Similarly, when the converted voltage of the resistance 7 is below the threshold value Ew. The output of the comparing circuit 8 is '1' and the multiplexer 93 is triggered to the side of a high- current attenuator 92. Consequently, the light output of the semiconductor laser during reproduction is made constant and a desired light output for recording is obtained over the entire light output range.

Title: Semiconductor laser
Inventor: ITOU KUNIO
IPC: H01S5/223
Filed: 1980-03-19
Abstract: PURPOSE:To realize single-mode oscillation between bend parts with a substrate having no difference in level by a method wherein the thickness of a part of the region of an active layer held between two bend parts is made larger than that of the part other than the above part. CONSTITUTION:The substrate 1 is not provided with any difference in level, while the active region 3 is not surrounded by the exactly bent parts, but is simply curved with some curvature. Moreover, it is unnecessary that the thickness of the active region 3 is uniform between the bend parts, and it is only required that a part thereof is thicker than the flat part thereof. To an extrame, the part between the bend parts is made to have the same thickness with that of the flat part. In addition, the thickness of the 1st clad layer 2 is not required to be thinned especially at the flat part, only requiring to be about 1mum. By this constitution, the index of the refraction between the bend parts of the active region becomes higher only slightly than that outside thereof and, even when the interval between the bend parts is increased to about 10mum, the oscillation of single mode is obtained, and thus manufacture of a laser element is facilitated.
