✦ Synopsis

We theoretically and experimentally demonstrate a novel dual-wavelength fiber Bragg grating fabricated using a double-exposure method. Our technique enables good control of the grating's reflectivity and separation of the two Bragg wavelengths. A grating with two equal transmission peaks of 20.5 dB is obtained with this method and the separation of the two Bragg wavelengths is about 0.8 nm. With this grating, an optical add-drop multiplexer (OADM) that allows dropping two fixed-wavelength channels is proposed.

## 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

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

We demonstrate a dual-stage gain-clamped erbium-doped fiber amplifier. The first-stage amplifier consists of a short length of erbium-doped fiber to produce low noise figures. The second-stage is constructed from a counter-propagating ring-laser, in which the signals and the lasing wavelength propag
