We convert a mid-infrared frequency comb to near-infrared wavelengths through sum-frequency generation with a 1.064 μm CW laser in an aperiodically poled ZnO:LiNbO(3) waveguide. Upconversion of light in the range of 2.5-4.5 μm to 0.76-0.86 μm is demonstrated in a single device, and the efficiency of the conversion is measured across this bandwidth. We additionally characterize the spatial mode ...

Multicolor infrared (IR) detectors are very important to advanced IR sensor systems. An IR detector with multicolor capability can offer a better target discrimination, tracking, and identification, as well as temperature determination. Multicolor IR sensors are also very useful in industry for gas leakage detection, chemical analysis, and for environmental sensing and control. As the IR techno...

In the fight against drug-resistant bacteria, accurate and high-throughput detection is essential. Here, a bimaterial microcantilever with an embedded microfluidic channel with internal surfaces chemically or physically functionalized with receptors selectively captures the bacteria passing through the channel. Bacterial adsorption inside the cantilever results in changes in the resonance frequ...

Objective To study the composition of intracavitary deposits on Essure® hysteroscopic sterilization devices. Design Case report. Setting Reproductive Medicine and Gynecology department of a University Hospital. Patients A 39 years old patient presenting with a request for surgical removal of Essure® sterilization devices. Diagnostic hysteroscopy showed a crystal like white deposit attache...

constants of crystalline WO 3 deposited by magnetron sputtering" (1999). Crystalline WO 3Ϫx is an infrared ͑IR͒ electrochromic material having possible applications in satellite thermal control and IR switches. Optical constants of electrochromic materials change upon ion intercalation, usually with H ϩ or Li ϩ. Of primary concern for device design are the optical constants in both the intercalat...

In this paper we report the fabrication, design and testing of an uncooled infrared imager based on an active pixel heat balancing technique. The imager is fabricated using a commercial CMOS process plus a simple electrochemical etch stop releasing step. The basic active pixel detector structure consists of a simple cascode CMOS amplifier in which the PMOS devices are built inside a thermally-i...

The paper reports on photoelectrical performance of the mid-wave infrared (MWIR) (111) HgCdTe high operating temperature (HOT) detector for the fast response conditions. Detector structure was simulated with software APSYS by Crosslight Inc. The detailed analysis of the time response as a function of device architecture and applied bias is performed pointing out optimal working conditions.

In this paper we describe a low-cost infrared optical device capable of tracking two targets with six DOF (Degrees Of Freedom) for interaction within both desktop and large projection applications. We use off-the-shelf components for the hardware and open-source libraries for the software.

We provide the first demonstration of a near infrared light driven water oxidation reaction in a molecule-based artificial photosynthetic device using an upconversion nano-photosensitizer. One very attractive advantage of this system is that using NIR light irradiation does not cause significant photodamage, a serious problem in molecular based artificial photosynthesis under visible light irra...
