Title: Control method of semiconductor laser
Inventor: OGITA SHOICHI
IPC: H01S5/12
Filed: 1987-08-05
Abstract: PURPOSE:To suppress the increase in width of the spectrum of light, which is generated in a semiconductor laser, by using a detecting and controlling system having a frequency band width, which can follow the fluctuation in carrier density, detecting the fluctuation in intensity of the output light from the laser, controlling a current, which is injected into the laser, and suppressing the fluctuation in carrier density. CONSTITUTION:The fluctuation in intensity of the output light from a semiconductor laser 11, is detected with, e.g. a light detecting element 12. A current, which is injected into the laser, is controlled with a current control circuit 14 through an amplifier 13. Namely, the frequency band width of this detecting and controlling system is set at a value reaching, e.g. several GHz-10GHz or more. The fluctuation in carrier density of the semiconductor laser is compensated. Thus, the increase in spectral width due to the fluctuation in carrier density, i.e., the increasing coefficient of the spectral width, can be suppressed.

Title: Transistor
Inventor: OYA SHUICHI
IPC: H01L21/8247
Filed: 1985-09-04
Abstract: PURPOSE:To form a longitudinally stacked ROM structure by setting the threshold voltage of a channel region higher than one after writing at the low level of the channel having memory function, coated with a floating gate electrode and lower than one after writing at the high level. CONSTITUTION:Since a transistor which has written is charged sufficiently negatively at a floating gate electrode 6 when a control gate electrode 12 is set to 0V, a channel region 5 becomes nonconductive. A channel region 10 is nonconductive, and the entire transistor becomes of a nonconductivity state. When the electrode 12 is set to 5V, if the electrode 6 is charged sufficiently negatively, the region 5 becomes nonconductive, but the region 10 becomes of a conducting state. Since the channel region having memory function and the channel region having approx. 1V of threshold voltage without memory function are presented in parallel, the entire transistor does not become 1V or higher of threshold voltage irrespective of the electron amount implanted to the electrode 6. Thus, a longitudinally stacking ROM structure can be electrically rewritten.
