TL;DR: In this paper, a novel photonic tunable microwave generation based on a dual-wavelength Q-switched Er-doped fiber laser is proposed and experimental demonstrated. But the proposed configuration requires two cascaded fiber Bragg gratings (FBG) as a cavity mirror, and a semiconductor saturable absorber mirror as another one.

TL;DR: In this article, a novel wideband and high gain waveguide-amplifier structure, which consists of a folded geometry erbium-ytterbium co-doped phosphate glass waveguide integrated with a cascaded multilayer medium thin-film filter (CMMTFF), is proposed.

TL;DR: In this article, a new S-type IR integrated waveguide amplifiers, based on erbium-ytterbium co-doped phosphate glass integrated with medium thin film filter, is proposed.

TL;DR: In this article, a novel optical microwave and millimeter generation by using single mode fiber FP cavity (SMFFPC) with pulse laser injection is proposed and experimentally demonstrated and the frequency of output signal is determined by the birefringence degree of the SMFFPC, a general relationship between output signal frequency of SM FFPC and birefeathering degree of single-mode fiber is derived.

TL;DR: In this paper, a stable three-wavelength ring-cavity laser based on a semiconductor optical amplifier with two fiber Bragg gratings (FBGs) and an external-injected distributed feedback (DFB) laser is proposed and experimentally demonstrated.
