Abstract

A Fabry‐Perot filter is realized by inscribing two identical 1 mm uniform Bragg gratings separated by 7.7 mm space in the hydrogen‐loaded photosensitive optical fiber. It is then incorporated with a tunable chirped fiber Bragg grating into a fiber ring cavity. Fourteen single‐wavelength lasings from 1552.186 nm to 1553.453 nm with average 97.5 pm spacing, and 13 pairs of dual‐wavelength lasings within the above wavelength range are achieved stably. This kind of laser will be very useful in applications requiring close‐spacing and tunable single‐ or dual‐wavelength components and systems. © 2008 Wiley Periodicals, Inc.

This paper reports on a Q-switched Er-doped fiber laser using the stress dependence of a wavelength of reflected light from fiber Bragg gratings. The laser cavity consists of a 0.5-m-long Er-doped fiber and two fiber gratings (FG) attached at both ends of the fiber. The pump laser is a 1.48 mm semic

## Abstract A simple switchable dual‐wavelength Er‐doped fiber‐ring laser using a fiber Bragg grating (FBG) written in high‐birefringence (HiBi) fibers is proposed. Due to the two‐peak reflections with orthogonal polarizations of the FBG, the polarization hole‐burning effect in the cavity is greatl

## Abstract A tunable narrow‐linewidth Er‐doped fiber ring laser using tunable fiber Bragger gratings (TFBGs) is proposed and demonstrated. The TFBG is fabricated with a strain‐induced uniform FBG, which acts as an excellent reflecting mirror. By putting longitudinal strain to the TFBG, an approxim
