The excited state properties of transition metal complexes have become a central focus of research owing to a wide range of possible applications that seek to exploit their luminescence properties. Herein, we use density functional theory (DFT), time-dependent DFT...

Temporal coupled mode theory of standing wave resonant cavities for infrared photodetection.

Optics express

Lesmanne E, De Lamaestre RE, Fowler D, Boutami S, Badano G.
PMID: 25837080
Opt Express. 2015 Mar 23;23(6):7385-99. doi: 10.1364/OE.23.007385.

Standing wave resonating cavities have been proposed in the past to increase the performance of infrared detectors by minimizing the volume of photogeneration, hence the noise, while maintaining the same quantum efficiency. We present an approach based on the...

A model-based 3D template matching technique for pose acquisition of an uncooperative space object.
