Picosecond photoinduced absorption measurements have been performed on four different (AlxGa1−x)0.5In0.5P fractal quantum well heterostructures. The results of these measurements reveal that, at early times following pulsed excitation, the carriers

The importance of research in optical nano-engineering today is comparable to that of research in semiconductors 60 years ago. Biologically inspired photoactive isomers are being engineered and incorporated into substrates to construct optically addr

In this paper, we describe a technique whereby cellular automata are used to rapidly scan hyperspectral medical images and quantify the extent of conditions of medical interest. The cellular automata population uses the condition of interest as food

Photodynamic Therapy (PDT) is a very exciting treatment modality that offers the possibility of a highly targeted treatment for cancer and other diseases. A major issue in the use of PDT is the inability to deliver the required dose of light to deep

The authors demonstrate lasing action in a novel microcavity laser which can be utilized for intracavity spectroscopy as well as high contrast imaging of small ({approximately} 10{mu}m) structures. The system can be easily visualized as a Fabry-Perot

We have developed a new intracavity laser technique that uses living or fixed cells at integral components of a laser. The cells are placed on an AlGaAs/GaAs surface-emitting semiconductor wafer and covered with a glass dielectric mirror to form a la
