BACKGROUND: Infectious travelers' diarrhea (TD) is a well-appreciated problem among service members serving abroad, particularly where infrastructure is limited due to ongoing combat operations, and efforts at sanitation and hygiene may not be considered an immediate priority. Bacterial and...

Self-gated mid-infrared short pulse upconversion detection for gas sensing.

Optics express

Wolf S, Trendle T, Kiessling J, Herbst J, Buse K, Kühnemann F.
PMID: 29041390
Opt Express. 2017 Oct 02;25(20):24459-24468. doi: 10.1364/OE.25.024459.

Pulsed nonlinear-optical upconversion is used for mid-infrared signal detection. A setup for both mid-infrared generation and upconversion based on a single pump laser enables sensitive light detection and is utilized for gas spectroscopy. With the demonstrated pulsed setup, quantum...

28 Gb/s direct modulation heterogeneously integrated C-band InP/SOI DFB laser.

Optics express

Abbasi A, Verbist J, Van Kerrebrouck J, Lelarge F, Duan GH, Yin X, Bauwelinck J, Roelkens G, Morthier G.
PMID: 26480161
Opt Express. 2015 Oct 05;23(20):26479-85. doi: 10.1364/OE.23.026479.

We demonstrate direct modulation of a heterogeneously integrated C-band DFB laser on SOI at 28 Gb/s with a 2 dB extinction ratio. This is the highest direct modulation bitrate so far reported for a membrane laser coupled to an...

False Discovery Rate Approach to Unsupervised Image Change Detection.

IEEE transactions on image processing : a publication of the IEEE Signal Processing Society

Krylov VA, Moser G, Serpico SB, Zerubia J.
PMID: 27448356
IEEE Trans Image Process. 2016 Oct;25(10):4704-4718. doi: 10.1109/TIP.2016.2593340. Epub 2016 Jul 19.

In this paper, we address the problem of unsupervised change detection on two or more coregistered images of the same object or scene at several time instants. We propose a novel empirical-Bayesian approach that is based on a false...

5 x 20 Gb/s heterogeneously integrated III-V on silicon electro-absorption modulator array with arrayed waveguide grating multiplexer.

Fu X, Cheng J, Huang Q, Hu Y, Xie W, Tassaert M, Verbist J, Ma K, Zhang J, Chen K, Zhang C, Shi Y, Bauwelinck J, Roelkens G, Liu L, He S.
PMID: 26191928
Opt Express. 2015 Jul 13;23(14):18686-93. doi: 10.1364/OE.23.018686.

We present a five-channel wavelength division multiplexed modulator module that heterogeneously integrates a 200 GHz channel-spacing silicon arrayed-waveguide grating multiplexer and a 20 Gbps electro-absorption modulator array, showing the potential for 100 Gbps transmission capacity on a 1.5x0.5 mm²...

Bose-Einstein condensation of cesium.

Science (New York, N.Y.)

Weber T, Herbig J, Mark M, Nägerl HC, Grimm R.
PMID: 12471267
Science. 2003 Jan 10;299(5604):232-5. doi: 10.1126/science.1079699. Epub 2002 Dec 05.

Bose-Einstein condensation of cesium atoms is achieved by evaporative cooling using optical trapping techniques. The ability to tune the interactions between the ultracold atoms by an external magnetic field is crucial to obtain the condensate and offers intriguing features...

Nanoscale architectures for molecular electronics: vibrational spectroscopy and structure of solid hexa-n-dodecyl-hexa-peri-hexabenzocoronene.

The Journal of chemical physics

Carminati M, Brambilla L, Zerbi G, Muellen K, Wu J.
PMID: 16238415
J Chem Phys. 2005 Oct 08;123(14):144706. doi: 10.1063/1.2046647.

The solid columnar discotic and liquid-crystalline phases formed by hexa-n-dodecyl-hexa-peri-hexabenzocoronene (HBC-C12) have been investigated by IR and Raman vibrational spectroscopies. IR spectra clearly show the two phase transitions at 42 and at 107 degrees C already reported in literature...

Observation of Feshbach-like resonances in collisions between ultracold molecules.

Physical review letters

Chin C, Kraemer T, Mark M, Herbig J, Waldburger P, Nägerl HC, Grimm R.
PMID: 15903917
Phys Rev Lett. 2005 Apr 01;94(12):123201. doi: 10.1103/PhysRevLett.94.123201. Epub 2005 Apr 01.

We observe magnetically tuned collision resonances for ultracold Cs2 molecules stored in a CO2-laser trap. By magnetically levitating the molecules against gravity, we precisely measure their magnetic moment. We find an avoided level crossing which allows us to transfer...

Long-duration gamma-ray bursts (GRBs) release copious amounts of energy across the entire electromagnetic spectrum, and so provide a window into the process of black hole formation from the collapse of massive stars. Previous early optical observations of even the...
