Micro-Raman spectroscopy in medicine

A potential role of optical technologies in medicine including micro-Raman spectroscopy is diagnosis of bacteria, cells and tissues which is covered in this chapter. The main advantage of Raman-based methods...

Nanobore Fiber Focus Trap With Enhanced Tunable Capabilities

Confinement in fiber traps with two optical fibers facing one another relies on balancing the optical forces originating from the interaction of a scattering micro-object with the light beams delivered...

Impact of deuteration on the ultrafast nonlinear optical response of toluene and nitrobenzene

Nonlinear pulse propagation inside highly nonlinear media requires accurate knowledge on the temporal response function of the materials used particular in the case of liquids. Here we study the impact...

Label-free CARS microscopy through a multimode fibre endoscope

Multimode fibres have recently been employed as high-resolution ultra-thin endoscopes, capable of imaging biological structures deep inside tissue in vivo. Here, we extend this technique to label-free...

Characterization of Fuel Gases with Fiber Enhanced Raman Spectroscopy

Common gaseous fuels are mixtures of several components. As the properties of the fuels can vary with the composition, but combustion needs to be stable, reliable analytical methods are highly sought after....

Light guidance in photonic band gap guiding dual-ring light cages implemented by direct laser writing

Efficient waveguiding inside low refractive index media is of key importance for a great variety of applications that demand strong light–matter interaction on small geometric footprints. Here, we demonstrate...

Richard g. Brereton: Chemometrics: data driven extraction for science, 2nd. ed.

Theoretical principles of Raman spectroscopy

This contribution reports on the theoretical foundations of Raman spectroscopy. Since the discovery of the Raman effect in 1928, Raman spectroscopy with its linear and nonlinear variants has established...

Liquid-Core Microstructured Polymer Optical Fiber as Fiber Enhanced Raman Spectroscopy Probe for Glucose Sensing

This work reports the development and application of two liquid-core microstructured polymer optical fibers (LCmPOF) with different microstructure sizes. They are used in a fiber-enhanced Raman spectroscopy...

Fiber Enhanced Raman Gas Spectroscopy for 18O-13C-labeling experiments

Stable isotopes are used in ecology to track and disentangle different processes and pathways. Especially for studies focused on the gas exchange of plants, sensing techniques that offer oxygen (O2) and...
