Special Issue "Tunable Lasers"
A special issue of Photonics (ISSN 2304-6732).
Deadline for manuscript submissions: 15 October 2019.
Lasers with a tunable output wavelength are necessary in many applications where a specific wavelength is required, but no fixed-wavelength laser exists for it, or the existing lasers do not provide the other needed performance parameters, such as the line width, pulse duration, or output power. Additionally, a number of analytical applications, as well as wideband spectral calibration and spectroscopy, call for laser sources with the ability for continuous wavelength tuning across a broad spectral range, while also delivering certain other radiation parameters, for example, the specified radiation coherence or repetition rate of ultra-short pulses. Modern tunable lasers are becoming more and more universal, offering not only wavelength tunability, but also many other competitive parameters. New broadband active media are being developed, and new solutions are being proposed on the basis of fibres, waveguides, micro-resonators, and other technologies. Novel methods of laser wavelength tuning are implemented, as are new ways of automatic control over radiation parameters, including machine learning and AI. The world of tunable lasers is dynamic, fascinating, and multi-faceted. Its unique concentration of advanced physics and technology are the reason tunable lasers are not only used as radiation sources for applications, but also as research platforms for the study of nonlinear, spatiotemporal, and other effects or phenomena. The Special Issue of the Photonics Journal will be dedicated to the results of the latest research and developments in the field of tunable lasers. We will consider contributed papers covering, but not limited to, the following topics:
- Tunable laser concepts and architecture
- Widely tunable lasers with no gap wavelength tuning
- Wavelength selection methods
- Methods of wavelength tuning/control and tuning techniques
- Elements of tunable lasers (wavelength-selective elements, broadband mirrors, etc.)
- Tunable lasers with new resonators: fiber, waveguide, WGM, cavity topologies, and so on.
- Novel tunable lasers: spaser, biolaser, organic semiconductor laser, and so on
- Tunability together with radiation special parameters capability
- Precision and fast wavelength tuning
- Theory of wavelength tuning and the modelling and optimization of tunable lasers
- Extended tunability by nonlinear techniques
- Closed/sealed/all-fiber cavity tunable laser oscillators
- Monolithically integrated tunable lasers
- Narrow-linewidth tunable laser and mode-hop-free tuning
- Ultra-short pulse tunable lasers and wavelength-tunable wave-breaking-free operation
- Swept and step-wavelength tunable lasers
- Multi-wavelength lasers and multi-line tuning
- Electronically/PC-controlled/automated tunable lasers
- Machine learning methods for the control of laser’s spectral parameters
- Tunable lasers as a research platform for general physical study (solitons, nonlinear and spatio-temporal dynamics, equilibrium states, extreme events, multistability and hysteresis phenomena, etc.)
- Design and engineering of tunable laser-based instrumentation
- Tunable laser applications.
