Paper Abstract

We present a programmable diode laser that can generate arbitrary optical pulse shapes and bursts with a timing resolution of 200 ps and 8 bit resolution for the amplitude level setting of each time bin. A PicoQuant developed ASIC is used as waveform generator. The use of a 5 GHz chip design and close arrangement of optimized electrical interfaces to the laser diode maintain the high frequency signal quality delivered into the laser diode. Fast current slopes result in picosecond gain switched operation while for nanosecond pulses undesired ringing effects at fast switch-on transients are reduced by defining specific current ramps.
