Rotating Polarization Coherent Anti-Stokes Raman Spectroscopy (RP-CARS) is a novel approach to CARS microscopy that takes advantage of polarizationdependent selection rules in order to gain information about molecule orientation anisotropy and direction within the optical point spread function. However, in the original implementation of this technique, the lockin amplifier-based acquisition was...
Contrast phase imaging at infrared wavelengths is achieved through an extrinsic Fabry-Perot cavity in optical fiber. The micro-cavity is realized by approaching a cleaved fiber to a distance of about few tens of microns from the surface under test. The probe is a single mode fiber and is fed by a low-coherence source. The information is extracted from the reflected spectrum, that starts to...
The well-known homoleptic iridium (III) complex Ir(ppz)3 which is only emissive in solution at low temperature has been investigated as dopant in a p − i stacked OLED architecture. Interestingly, while using this phosphor as a single emitter, awhite OLED was obtained. Emission colour was determined as being concentration and thickness-dependent.
Generalized Phase Contrast (GPC) is an efficient method for generating speckle-free contiguous optical distributions. It has been used in applications such as optical manipulation, microscopy, optical cryptography and more contemporary biological applications such as twophoton optogenetics or neurophotonics.Among its diverse applications, simple efficient shapes for illumination or excitation happen...
Liquid crystal droplets are widely used in optics and photonics applications. They can act as simple resonators or be arranged in interconnected periodic configurations when their external dimension are similar. In this work we optically analyze and describe the microfluidic generation of liquid crystal droplets in a thermally stabilized environment, namely water, which enables a narrow droplets diameter...
