Application of spectral-focusing-CARS microscopy to pharmaceutical sample analysis
We implement spectral-focusing-CARS hyperspectroscopy to characterize pharmaceutical samples. The use of a dynamically-power-tuned supercontinuum seeding method combined with epi-detection of the CARS signals allows for broadband hyperspectroscopy and ...

Generation and Direct Detection of Broadband Mesoscopic Polarization-Squeezed Vacuum [PDF]
Using a traveling-wave OPA with two orthogonally oriented type-I BBO crystals pumped by picosecond pulses, we generate vertically and horizontally polarized squeezed vacuum states within a broad range of wavelengths and angles.

A match coefficient approach for damage imaging in structural components by ultrasonic synthetic aperture focus [PDF]
Ultrasonic Synthetic Aperture Focus (SAF) techniques are commonly used to image structural defects. In this paper, a variation of SAF based on ideas borrowed from Matched Field Processing (MFP) is evaluated to reduce artifacts and sidelobes of the ...

Improving Photoacoustic-guided Focusing in Scattering Media by Spectrally Filtered Detection
We experimentally and numerically study the potential of photoacoustic-guiding for light focusing through scattering samples via wavefront-shaping and iterative optimization.

Temporal recompression through a scattering medium via a broadband transmission matrix
The transmission matrix is a unique tool to control light through a scattering medium. A monochromatic transmission matrix does not allow temporal control of broadband light.

Theory of Two-Photon Interactions with Broadband Down-Converted Light and Entangled Photons [PDF]
When two-photon interactions are induced by down-converted light with a bandwidth that exceeds the pump bandwidth, they can obtain a behavior that is pulse-like temporally, yet spectrally narrow.

Polarization dependent image artifacts are common in optical coherence tomography imaging. Polarization insensitive detection scheme for swept source based optical coherence tomography systems is well established but is yet to be demonstrated for all ...

Architectures and Key Technical Challenges for 5G Systems Incorporating Satellites [PDF]
Satellite Communication systems are a promising solution to extend and complement terrestrial networks in unserved or under-served areas. This aspect is reflected by recent commercial and standardisation endeavours. In particular, 3GPP recently initiated
