Title: Fabrication of semiconductor laser
Inventor: TERAKADO TOMOJI
IPC: H01S5/00
Filed: 1992-04-28
Abstract: PURPOSE:To mass produce high performance semiconductor lasers excellent in environmental resistance at low cost. CONSTITUTION:Two stripe masks 2 formed in (011) direction on (100) face of a semiconductor substrate 1 composed of n-InP are employed as selection masks in the formation of an active layer stripe 13 through metal organic vapor phase epitaxial growth, the stripe 2 is then removed and filling growth is performed. Since metal organic vapor phase epitaxial growth is employed, large area uniform growth is realized on a circular wafer having diameter or two inches or more. Furthermore, since the active layer stripe 13 is formed through selective growth employing a mask, side wall of the active layer stripe 13 can be made smooth in the order of atomic layer. Since waveguides of semiconductor laser do not scatter and loss thereof is reduced, oscillation threshold current and operating current of semiconductor laser can be lowered.

IPC: G11B7/09
Filed: 1986-05-14
Abstract: PURPOSE:To eliminate an oscillation phenomenon at the end of rough access, to eliminate misreading of an address, and to prevent a rotation waiting time from becoming long by constituting one tracking actuator coil so that it is turned off freely from a driving circuit. CONSTITUTION:In a stationary servo state, switches S1-S6 are 100100 (1: on, 0: off), coils L1 and L2 are driven in series to follow up a track error signal, and the generated counter electromotive force of the coil L1 exerts no influence on a phase compensating circuit. In access mode, on the other hand, the switches S1-S6 become 011001, the coil L1 generates the counter electromotive force according to the oscillation of the tracking actuator; and the voltage drop across a resistance R is fed as speed information back to a phase compensating circuit and a driving circuit drives only the coil L2. Therefore, the coil L1 is disconnected from the driving circuit and allowed to function as a speed sensor, thereby preventing the tracking actuator from oscillating.
