Three-port beam splitters-combiners for interferometer applications

, 2006
We derive generic phase and amplitude coupling relations for beam splitters-combiners that couple a single port with three output ports or input ports, respectively.

Germanium‐Based Mid‐Infrared Integrated Photonics

Laser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

High-extinction-ratio resonant cavity polarizer for quantum-optics measurements [PDF]

, 2007
The use of a high-finesse Fabry-Perot ring cavity with an odd number of reflections as a high-extinction-ratio resonant polarizer is shown. Experimental results from quantum-noise measurements using resonant cavities as spatial and spectral filters and ...

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking

Laser &Photonics Reviews, EarlyView.
Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Demonstration of 3-port grating phase relations

, 2006
We experimentally demonstrate the phase relations of 3-port gratings by investigating 3-port coupled Fabry-Perot cavities. Two different gratings which have the same 1st order diffraction efficiency but differ substantially in their 2nd order diffraction

Nondestructive Quantification of Water Ingress in PV Modules via Spectroscopic and Chemical Analysis for Enhanced Quality Assurance and On‐Site Inspection

Progress in Photovoltaics: Research and Applications, EarlyView.
This study presents a novel, nondestructive in situ method to quantify water ingress using near‐infrared absorption (NIRA) spectroscopy, calibrated with absolute water content via Karl–Fischer titration (KFT). The presented approach offers a powerful quality assurance and inspection tool for module manufacturers and solar developers, supporting ...

All fiber, low threshold, widely tunable single-frequency, erbium-doped fiber ring laser with a tandem fiber Fabry–Perot filter [PDF]

, 1991
An all fiber, widely tunable, single-frequency, erbium-doped fiber ring laser was constructed with a threshold pump power as low as 10 mW. Tuning over more than 30 nm was obtained by applying 0 to 17 dc V to an intracavity fiber Fabry–Perot filter ...
