We report wide wavelength tuning in a double-clad ytterbium-doped fiber laser. The laser cavity consists of an array of broadband high-reflection fiber Bragg gratings and a bulk grating as output coupler and wavelength selection element. The proposed fiber laser configuration combines low intra-cavi

A new method for fabricating double fiber Bragg gratings at the same location on a fiber is described. Two series of refractive index change in a fiber, not similar to the normal fiber grating, have been realized by a Fresnel prism interferometer. As a result, the transmission spectrum of the fiber
## Abstract The performances of gain and noise figure of an Lβband EDFA utilizing a ring laser cavity is demonstrated. It uses a fiber Bragg grating (FBG), arranged to propagate in opposition to the amplifier signal by a pair of circulators, to provide laser feedback. A flatβgain spectrum with less
Conical microlenses fabricated at the end of single-mode fibers can increase the coupling efficiency between fibers and laser diodes. In this letter, we present, for the first time, a theoretical analysis of the coupling efficiency between a laser diode and a conically lensed fiber, taking into acco
## Abstract The objective of our work is to conduct a theoretical analysis to determine the coupling efficiency between a laser diode (LD) and a hemispherically lensed tapered singleβmode fiber (SMF), which takes into account the effect of spherical aberration on the lens surface. The results obtai
## Abstract A novel allβoptical technique for microwave generation using photonic crystal fiber Brillouin laser is presented, and a 9.78βGHz microwave signal generator based on the Brillouin laser is experimentally realized. The Brillouin laser is based on a fiber FabryβPerot cavity with fiber Brag
