Third-harmonic generation with tailored modes in liquid core fibers with geometric birefringence
Geometrically induced birefringence represents a pathway for precisely engineering the modes in fibers and is particularly relevant for applications that crucially depend on modal dispersion. Here liquid...
PublicationsInfluence for nanobody binding on fluorescence emission, mobility, and organization of GFP-tagged proteins
Advanced fluorescence microscopy studies require specific and monovalent molecular labeling with bright and photostable fluorophores. This necessity led to the widespread use of fluorescently labeled nanobodies...
PublicationsHigh Enhancement Strain Sensor Based on Vernier Effect Using 2-Fiber Loop Mirrors
In this letter, a strain sensor with high sensitivity enhancement using a special case of Vernier effect is presented. The sensor configuration is composed of two-fiber loop mirrors in a cascaded configuration...
PublicationsAptasensor for the detection of Methicillin resistant Staphylococcus aureus on contaminated surfaces
There is mounting evidence that contaminated hospital environment plays a crucial role in the transmission of nosocomial pathogens such as MRSA. The institution of infection control protocols is predicated...
PublicationsNanostructure-Empowered Efficient Coupling of Light into Optical Fibers at Extraordinarily Large Angles
Coupling of light from free space to optical fibers is essential for many applications, while commonly used step-index optical fibers provide insufficient coupling efficiencies especially at large angles...
PublicationsTowards an Interpretable Classifier for Characterization of Endoscopic Mayo Scores in Ulcerative Colitis Using Raman Spectroscopy
Ulcerative colitis (UC) is one of the main types of chronic inflammatory diseases that affect the bowel, but its pathogenesis is yet to be completely defined. Assessing the disease activity of UC is vital...
PublicationsSynthesis, characterization and optical properties of ytterbium (III) orthophosphates and their incorporation in different glass matrices
Nanosized hydrated YbPO4•nH2O powders were prepared by precipitation from aqueous solutions. It is shown that the structure, optical properties, and size of the raw particles can be further tailored...
PublicationsUnidirectionality in Bidirectional Fiber Ring Lasers: An Instability Approach
Fiber ring laser schemes are very attractive as they allow a fully integrated system structure. Albeit having many benefits one major shortcoming of ring structures is the native power division due to...
PublicationsEffect of Fiber Length and Loss on the Threshold of Unidirectional Lasing in a Reciprocal All-Fiber Ring Laser
We recently demonstrated unidirectional lasing in a reciprocal all fiber ring laser at full laser operation. With this manuscript we discuss the influence of length and fiber loss on the triggering of...
PublicationsInfluences on the Direction Probabilities for the Direction Instability Phenomenon in Fiber Ring Lasers
Direction instability is a new phenomenon where a reciprocal fiber ring laser initially operates in both directions but spontaneously turns of one lasing direction and switches to unidirectional mode...
