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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
