We demonstrate mid-infrared quantum cascade detectors (QCD) operating in the strong light-matter coupling regime. They operate around $\lambda = 10~\mu m$ with a minimum Rabi splitting of 9.3 meV. A simple model based on usual description transport QCDs does not reproduce polaritonic features photo-current spectra. On contrary, more refined approach, semi-classical coupled modes theory, is capa...

Silicon-based semiconductor technology has made great breakthroughs in the past few decades, but it is reaching physical limits of Moore’s law. In recent years, presence two-dimensional (2D) materials was regarded as an opportunity to break limitation traditional silicon-based optoelectronic devices owing their special structure and superior properties. consideration widely studied hybrid integ...

We demonstrate polarization-dependent photo-response enhancement in metamaterial-coupled quantum dots-in-a-well infrared detectors. A gold split-ring resonator metamaterial layer was patterned by electronbeam lithography in the detector aperture. In this integrated structure, the detector spectral response is given by the convolution of the metamaterial field enhancement and the original detect...

The majority of natural sources (black-bodies, fluorescent bulbs, etc) generate completely un-polarized light; the majority of detectors (eyes, photo-cameras, photomultipliers, etc) are polarization-insensitive. To reflect this, we attempt to describe approximately electromagnetic waves without polarization. Corresponding scalar equations are non-trivial modifications of standard d’Alembert and...

We discuss a new method for realizing number-resolving and non-demolition photo detectors by strong coupling of light to individual single photon emitters, which act as strong optical nonlinearities. As a specific application we show how these elements can be integrated into an error-proof Bell state analyzer, whose efficiency exceeds the best possible performance with linear optics even for a ...

In the T2K near neutrino detectors, about 60 000 Hamamatsu Multi-Pixel Photon Counters (MPPCs) will be used. The mass production of MPPC has started in February 2008. In order to perform quality assurance and to characterize each device, we have developed an MPPC test system. For each MPPC, gain, breakdown voltage, noise rate, photo detection efficiency, and cross-talk and after-pulse rate are ...

Here we report a racetrack resonator laser integrated with two photo-detectors on the hybrid AlGaInAs-silicon evanescent device platform. Unlike previous demonstrations of hybrid AlGaInAs-silicon evanescent lasers, we demonstrate an on-chip racetrack resonator laser that does not rely on facet polishing and dicing in order to define the laser cavity. The laser runs continuous-wave (c.w.) at 159...

This paper presents the first participation of the Pattern Recognition and Application Group (PRA Group), and the Ambient Intelligence Lab (AmILAB) at the ImageCLEF 2012 Photo Flickr Concept Annotation Task. In this task, the teams’ goal is to detect the presence of 94 concepts in the images, and to provide a confidence score related to the confidence of the decision of each concept detector. W...
