Photonic crystal fiber based dual-wavelength Q-switched fiber laser using graphene oxide as a saturable absorber
TL;DR: A Q-switched dual-wavelength fiber laser with narrow channel spacing with substantial potential for use in applications that require longer duration pulsed outputs such as in range finding and terahertz radiation generation is proposed and demonstrated.

TL;DR: In this paper, a new approach for the generation of an optical frequency comb, based on chirping of modulators, is proposed and numerically demonstrated, which includes two cascaded Mach-Zehnder Modulators (MZMs), a sinusoidal wave oscillator, and an electrical time delay.
Journal ArticleDOI
Electrically Tunable Microfiber Knot Resonator Based Erbium-Doped Fiber Laser
TL;DR: In this article, a tunable fiber laser was demonstrated using a microfiber knot resonator structure made by a highly doped Erbium fiber, which achieved a stable laser output at the 1533-nm region with a signal to noise ratio of 15 dB using a 63mW 980-nm pump power.
Journal ArticleDOI
An efficient multiwavelength light source based on ASE slicing
TL;DR: In this article, a multiwavelength light source based on a flat-gain erbium-doped fiber amplifier and loop mirror is experimentally demonstrated for single-pass and double-pass scheme.
Journal ArticleDOI
Generation of Q-switched Pulses in Thulium-doped and Thulium/Holmium-co-doped Fiber Lasers using MAX phase (Ti 3 AlC 2 ).
TL;DR: The performance of the Ti3AlC2 based SA for Q-switching operation indicates the high potential of other MAX phase materials to serve as SAs in future photonics systems.
