Abstract
A discretely tunable Er‐doped fiber‐ring laser using a fiber Mach‐Zehnder interferometer (MZI) and a tunable fiber Bragg grating (FBG) is proposed. In this scheme, the combination of MZI and FBG acts as a discrete wavelength selector. Analysis of its transmission function shows that discrete wavelength tuning can be realized, and experiments demonstrate 64 single‐mode outputs with a mode spacing of 181.7 pm, and the output power is quite stable in the whole tuning range. © 2009 Wiley Periodicals, Inc.

We demonstrate pulsewidth tunable Q-switched erbium fiber lasers using in-line high extinction ratio (> 30 dB) abrupt-tapered fiber Mach-Zehnder block filter and tunable Fabry-Perot filter in laser cavity. The pulsewidth can be tuning over 78 ns -23 ms. Voltage, mV
## 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
## Abstract We proposed and demonstrated a room‐temperature multiwavelength Yb‐doped fiber ring laser with high stability based on a Mach‐Zehnder interferometer by exploiting spatial hole burning and polarization hole burning effects, from which stable eight lasing wavelengths is obtained. The numb
