GCSR laser frequency drift compensation using optimized current waveform on one single electrode

GCSR laser frequency drift compensation using optimized current waveform on one single electrode

In this paper we present a new method to compensate the whole frequency deviation due to thermal drift during wavelength switching for a semiconductor laser based on launching a distorted current pulse just on one of the tuning electrodes of the laser. We experimentally confirm its efficiency compar...

Zusammenfassung:In this paper we present a new method to compensate the whole frequency deviation due to thermal drift during wavelength switching for a semiconductor laser based on launching a distorted current pulse just on one of the tuning electrodes of the laser. We experimentally confirm its efficiency compared with the time constant technique.
