Multi-Wavelength Fiber Lasers

چکیده
Nowadays, multiwavelength lasers are of great interest for telecommunications and sensors multiplexing. These lasers also have a great potential in the fiber-optic test and measurement of WDM components. The requirements for such optical sources are: a high number of channels over large wavelength span, moderate output powers (of the order of 100μW per channel) with good optical signal to noise ratio (OSNR) and spectral flatness, single longitu‐ dinal mode operation of each laser line, tunability and accurate positioning on the ITU frequency grid. Reaching all these requirements simultaneously is a difficult task, and many different approaches using semiconductor or erbium-doped fiber technology have been proposed and experimented in order to obtain multiwavelength laser oscillation.

Integrated silica microdisk resonators can be used to create a variety of very high performance spectral filters. These filters can control the spectral emission of an erbium doped fiber laser. By modifying the number and sizes of the microdisks constituting these filters it is possible to produce single wavelength, periodic multi-frequency and non-periodic multi-wavelength fiber lasers.

The output pulse duration is around 6 ps with a spec...

A multi-wavelength tunable fiber laser based on the use of an Opto-VLSI processor in conjunction with different optical amplifiers is proposed and experimentally demonstrated. The Opto-VLSI processor can simultaneously select any part of the gain spectrum from each optical amplifier into its associated fiber ring, leading to a multiport tunable fiber laser source. We experimentally demonstrate ...

A stable and self-starting femtosecond breathing-pulse Yb-fiber oscillator is reported, modelocked using the nonlinear polarisation evolution mechanism.

متن کاملStability analysis of second order pulsed Raman laser in dispersion managed systems
Wavelength tunable synchronous pulse sources are highly desirable for spectroscopy and optical diagnostics. The common method to generate short pulses in the fiber is the use of nonlinear induced spectral broadening which result in soliton shaping in anomalous dispersion regime. However, to generate ultra-short pulses, broadband gain mechanism is also required. In recent years, Raman fiber lase...
