Original abstract

A MHz akinetic swept source is demonstrated by incorporating a commercial Erbium Doped Fiber Amplifier into a fiber laser cavity assembly. Such laser is brought into mode-locking based on nonlinear polarization rotation (NPR). After the laser, a dispersion compensating fiber is employed to time-stretch the broadband pulses obtained. Different cavity lengths are evaluated, leading to sweeping rates from 0.9 MHz to 9.65 MHz. A maximum of 67 nm bandwidth has been achieved. The swept source has been characterized using a Master-Slave procedure, obtaining an almost linear sweep.
