Special Issue Information

Dear Colleagues,

Tunable laser technology has advanced significantly, providing versatile light sources with adjustable wavelengths. These lasers are integral to telecommunications, enabling high-speed data transmission through wavelength-division multiplexing. In spectroscopy, they facilitate precise measurements of molecular absorption spectra for chemical analysis. Additionally, tunable lasers play crucial roles in material processing, offering control in laser ablation and micro-structuring. In medical diagnostics, they enable non-invasive imaging modalities like optical coherence tomography for detailed tissue imaging. Tunable lasers continue to drive innovation across industries, offering tailored solutions for diverse applications.

This Special Issue on 'Recent Advancements in Tunable Laser Technology' invites submissions of basic, methodological, and cutting-edge research, including regular and review papers, contributing to the following:

  • Creation and validation of single or multiple spectroscopic instruments for diverse applications.
  • Innovation in materials for generating tunable laser technology.
  • Advancements in multispectral lasers and methods for scalability.
  • Validation of methods and tools utilized or developed for tunable laser technology applications.
  • Review of current status.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Photonics is an international peer-reviewed open access monthly journal published by MDPI.

Abstract
As global internet traffic continues to increase, technologies for generating high-frequency signals, such as sub-terahertz (sub-THz) bands, through photonics are gaining attention. In this study, we demonstrate the generation of millimeter waves at approximately 17 GHz and sub-THz waves at approximately 300 GHz [...] Read more.
As global internet traffic continues to increase, technologies for generating high-frequency signals, such as sub-terahertz (sub-THz) bands, through photonics are gaining attention. In this study, we demonstrate the generation of millimeter waves at approximately 17 GHz and sub-THz waves at approximately 300 GHz by converting the frequency difference of a two-wavelength tunable laser, fabricated using silicon photonics, into an optical–electrical signal. This device is expected to be used as a compact and low power consumption, two-wavelength tunable light source for THz wave transceivers. Full article

In this demonstration, we present two erbium-doped fiber (EDF) lasers, with series and parallel three sub-ring configurations, respectively, to achieve tunable channel output and stable single longitudinal mode (SLM) operation in the L-band range. Here, the fiber ring cavity contains the L-band EDF as a gain medium. Based on the measured results of the two quad-ring structures of the EDF lasers, tunable output bandwidth for the two lasers can be obtained from 1558.0 to 1618.0 nm simultaneously. All the 3 dB linewidths measured for both fiber lasers are 312.5 Hz over the effective wavelength output range. Furthermore, the related optical signal-to-noise ratio (OSNR), output power, output stabilities of the central wavelength and power, and equal output power range of the two proposed EDF lasers are also examined and discussed.
