Ultrashort pulse generation from binary temporal phase modulation

We propose and numerically validate an all-optical scheme to generate a train of optical pulses. Modulation of a continuous wave with a periodic binary temporal phase pattern followed by a spectral phase shaping enables us to obtain ultrashort pulse trains. An ideal step phase profile as well as a profile arisen from a bandwidth-limited device is investigated. Analytical guidelines describing pulse train formation and their characteristics are provided. Pulses with a duration of a few picoseconds at a repetition rate of 10 GHz can be expected for realistic experimental conditions.

Automated summary

An all-optical scheme for generating a train of optical pulses is proposed and numerically validated in this study. By modulating a continuous wave with a periodic binary temporal phase pattern followed by spectral phase shaping, ultrashort pulse trains can be obtained. The study provides analytical guidelines for describing pulse train formation and their characteristics, indicating that pulses with a duration of a few picoseconds at a repetition rate of 10 GHz can be expected under realistic experimental conditions.
