A thermo-optically tunable multimode interference fiber laser is demonstrated. The laser emission can be easily tuned trough the C-band by simply changing the temperature around the multimode fiber liquid cladding of the filter. ©2011 Optical Society of America OCIS codes: (060.2410) Fibers, Erbium; (060.2310) Fiber Optics; (140.3600) Lasers Tunable; (060.4510) Optical communications

Effects of radiation on sensing and data transmission components are of great interest in many applications including homeland security, nuclear power generation, and military. A new type of microstructured optical fiber (MOF) called the random hole optical fiber (RHOF) has been recently developed. The RHOFs can be made in many different forms by varying the core size and the size and extent of...

In spite of excellent corrosion resistance, good ductility and low cost of AISI 316 austenitic stainless steel, the low hardness and poor mechanical charecteristic of material restricts its applicability in several industrial services. To improve upon mechanical properties AlFeCuCrCoNi-WC10 high-entropy alloy coatings were deposited via laser cladding on austentic stainless steel AISI 316 subst...

The effective index change and form birefringence are calculated in UV-exposed fibers using a high-order vectorial finite element method. The birefringence is compared in optical fibers with and without photosensitive inner cladding.

Current research efforts are focussed on overcoming the apparent limits of communication in single mode optical fibre resulting from distortion due to fibre nonlinearity. It has been experimentally demonstrated that this Kerr nonlinearity limit is not a fundamental limit; thus it is pertinent to review where the fundamental limits of optical communications lie, and direct future research on thi...

C. Michel, S. Tascu, V. Doya, O. Legrand, F. Mortessagne In this paper, we present a non-standard fibre amplifier specially designed to amplify scar modes of a multimode chaotic optical fibre. More precisely, we introduce Ytterbium in the optical fibre as a gain medium localised on the maximum of intensity of the scar modes. After briefly recalling the relevance of a chaotic optical fibre as a ...
