Abstract

We propose a new method for obtaining high-power short optical pulses without trailing pulses from an actively mode-locked laser diode. To quench the residual optical gain, a part of the output is reflected back into the laser diode with the orthogonal polarization and the appropriate time delay. A numerical analysis using traveling-wave rate equations shows that trailing pulses caused by both the excess gain and the residual reflection at the laser diode facet are drastically suppressed.
