Electronically implementation and detection of pulse laser from continuous laser diode

الملخص EN

Abstract: This research aims to design a high-speed laser diode driver and photodetector, the result is the design of the high-speed laser diode driver with a short pulse of 10 ns at 30 KHz frequency and the delivered maximum pulse voltage is 5.5 mV.

Also, its optical output power of the laser diode driver is about 2.529 mW for the centroied wavelength 1546.7 nm with FWHM of 286 pm and (1270-1610) nm.

The design of the circuit based on bipolar transistor where the input pulse signal is simply generated by an arduino kit with 15 kHz frequency and then compensated to trigger to small signal amplifier which was is simply NPN C3355 transistor and the output is a current driver to the laser diode.

OptiSystem software and Electronic Workbench tools were used for the design of high speed laser diode diver and its simulation.
