115?kHz tuning repetition rate ultrahigh-speed wavelength-swept semiconductor laser

We demonstrate an ultrahigh-speed wavelength-swept semiconductor laser using a polygon-based wavelength scanning filter. With a polygon rotational speed of $900\text{\hspace{0.17em} revolutions}\text{per}\text{second}$, a continuous wavelength tuning rate of $9200\mathrm{nm}∕\mathrm{ms}$ and a tuning repetition rate of $115\mathrm{kHz}$ were achieved. The wavelength tuning range of the laser was $80\mathrm{nm}$ centered at $1325\mathrm{nm}$, and the average polarized output power was $23\mathrm{mW}$.
