Title: Driving method for semiconductor light-emitting element
Inventor: SHIBATA ATSUSHI
IPC: H01S5/026
Filed: 1985-02-13
Abstract: PURPOSE:To enable high-speed direct modulation by a method wherein P-N junction consisting of the first and the second semiconductor layers is impressed by forward voltage and is made to emit light, and P-N junction consisting of the first and the third semiconductor layers is impressed by backward voltage and is stopped emitting light, and thereby optical ON-OFF control is performed. CONSTITUTION:Light emission is generated inside the first semiconductor layer supplying forward current by bias voltage, which impresses between the first and the second semiconductor layers of a semiconductor light-emitting element and as it is, electrons injected from the second semiconductor layer by bias voltage, which impresses between the first and the third semiconductor layers, are absorbed in the third semiconductor layer, thereby the light emission is stopped. That is, since the electric current flowing between the first and the second semiconductor layers by voltage impressing between the first and the third semiconductor layers is switched to between the first and the third semiconductor layers, the direction of collector current at this time is switched from minus to plus. By using such a driving measure, light emission can be made to follow high frequency signals without accumulation of carrier in an active layer. Thereby, high-speed direct modulation of semiconductor laser can be performed easily.
