Fiber Lasers, Photonic Crystals, and Optical Fiber Sensors
This community develops laser sources, photonic structures, and sensing systems built around optical fibers, primarily for telecommunications, precision measurement, and medical diagnostics.
The work centers on the design and optimization of fiber lasers, including mode-locked and Q-switched systems using saturable absorbers and rare-earth-doped fibers such as erbium and thulium. A significant portion of the research focuses on photonic crystal fibers and Bragg gratings for creating specialized optical devices. These components are applied in high-sensitivity sensing for temperature, magnetic fields, and chemical concentrations, as well as in surface plasmon resonance biosensors for detecting biological markers. The community also investigates nonlinear optical effects and pulse generation techniques to improve the performance and tunability of these photonic systems.
The largest share of the community's output is found in erbium research, accounting for 40.9% of all erbium research, and 9,980 papers here. Thulium and ytterbium also represent substantial portions of their respective element research, with shares of 30.6% and 25.7%.
The community comprises 74,800 papers, publishing most frequently in Optics Letters, Optics Express, and Optical Fiber Technology.
Recent work includes the development of broadband optical fibers with ultra-low attenuation, calibration-free gas concentration measurement via thermoelastic spectroscopy, and machine learning-enhanced surface plasmon resonance biosensors for cancer cell detection.
