Small-size microlens characterization by multiwavelength high-resolution interference microscopy

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

Microlenses are widely studied in two main areas: fabrication and characterization. Nowadays, characterization draws more attention because it is difficult to apply test techniques to microlenses that are used for conventional optical systems. Especially, ...

New Inks for the Direct Drop-on-Demand Fabrication of Polymer Lenses

Jürgen Brugger, Cristina Martin Olmos, Joo Yeon Kim

The advent of cell phone cameras extensively pushed market needs for micro lenses and supported developments like the Wafer-Level-Camera Technology [1]. Different optical applications and patterning methods for micro lenses require different sets of materi ...

Near-field polarization measurements based on two arbitrary, orthogonal optical field components

Olivier Martin, Hans Peter Herzig, Libo Yu, Tristan Sfez, Daniele Brunazzo, Francesco Michelotti

Using a multi-heterodyne scanning near-field optical microscope, we detect two arbitrary, orthogonal components of the near field. A numerical treatment of the experimental data allows the retrieval of the transverse and longitudinal components of the mode ...

Spatio-temporally focused femtosecond laser pulses for nonreciprocal writing in optically transparent materials

Yves Bellouard, Erica Kathleen Block

Simultaneous spatial and temporal focusing (SSTF) provides precise control of the pulse front tilt (PFT) necessary to achieve nonreciprocal writing in glass wherein the material modification depends on the sample scanning direction with respect to the PFT. ...

Digital holographic microscopy investigation of second harmonic generated at a glass/air interface

Christian Depeursinge, Nicolas Pavillon, Jonas Kühn, Etienne Shaffer

Optical second harmonic generation, thanks to its coherent nature, is a suitable signal for interferometric measurements, such as digital holography: a well-established imaging technique that allows recovering complex diffraction wavefields from which it i ...

Polarization Evolution of Stimulated Brillouin Scattering Amplified Signals in Standard Fibers

Luc Thévenaz

The polarization evolution of stimulated Brillouin scattering amplified signals in the presence of fiber birefringence is examined in analysis, simulation and experiment. The signal polarization is drawn towards the conjugate of the pump polarization. ...

Instrument-independent specification of the diffraction geometry and polarization state of the incident X-ray beam

This work augments the proposal of Schwarzenbach & Flack [J. Appl. Cryst. (1989), 22, 601-605], who have advocated the use of a diffractometer-independent definition of the azimuthal angle

\psi

to specify the diffractiongeometry of a Bragg reflection. It ...

Time-domain distributed sensor with 1 cm spatial resolution based on Brillouin dynamic gratings

Luc Thévenaz, Sang Hoon Chin, Nikolay Primerov, Kwang-Yong Song

We propose and experimentally demonstrate the highest-resolution BOTDA system ever reported using Brillouin dynamic grating in a polarization-maintaining fiber (PMF). Acoustic waves containing the information of local Brillouin frequency are generated by a ...

Polarization-induced distortion in stimulated Brillouin scattering slow-light systems

Luc Thévenaz, Sang Hoon Chin

The vector analysis of stimulated Brillouin scattering amplification in birefringent fibers is extended to include signal pulses. The analysis finds that the different slow-light delays experienced by the states of polarization corresponding to maximum and ...

Weak signals as a flexible framing space for enhanced management and decision-making

Pierre Rossel

This paper revisits theories of weak signal analysis using the concepts of 'framing' and 'meta-framing' to provide an enriched methodological environment for management and decision-making in turbulent contexts. This attempt takes place within the effort t ...
