Title: Semiconductor laser drive device
Inventor: MINEMURA KOUICHI
IPC: H04B10/50
Filed: 1982-08-10
Abstract: PURPOSE:To improve high speed direct modulation characteristic by a method wherein a parallel circuit with a resistor and a capacitor is inserted between one terminal of a semiconductor laser and the drain terminal of a FET, and driven by inpressing a fixed bias voltage onto the source. CONSTITUTION:The negative bias -VB is impressed onto the source of the FET, a pulse signal is inputted to the gate via the resistor 3 from the terminal 4, amplified 1 resulting in passage through the parallel circuit with the resistor 5 and the capacitor 6, and given to the cathode of the laser 2. From the terminal 9, a DC bias current lower than the threshold value is supplied to the laser 2 via a series circuit with a coil 7 and a resistor 8. The capacitor 6 adds back spike current to the pulse signal, and an attenuation time constant is determined by the product with the resistor 5. The back spike current cancels excess carriers remaining at the pulse breaking part in the carrier injected into the laser, compensates waveform strain of a large breaking time, and compensate the jitter at a photo pulse rise part. Therefore, high speed modulation of several hundred M- b/s or more can be performed well even in case of the delay time of 3ns or more by means of a DC bias current less than the threshold value, and the waveform strain of photo pulse is small.
