Organometal halide perovskites as visible-light sensitizers for photovoltaic cells.
Journal of the American Chemical Society, 2009Two organolead halide perovskite nanocrystals, CH(3)NH(3)PbBr(3) and CH(3)NH(3)PbI(3), were found to efficiently sensitize TiO(2) for visible-light conversion in photoelectrochemical cells.

Orbital angular momentum of light and the transformation of Laguerre-Gaussian laser modes.
Physical Review A. Atomic, Molecular, and Optical Physics, 1992Laser light with a Laguerre-Gaussian amplitude distribution is found to have a well-defined orbital angular momentum. An astigmatic optical system may be used to transform a high-order Laguerre-Gaussian mode into a high-order Hermite-Gaussian mode ...

Kindling the Darkness: A Practical Low-light Image Enhancer
ACM Multimedia, 2019Images captured under low-light conditions often suffer from (partially) poor visibility. Besides unsatisfactory lightings, multiple types of degradations, such as noise and color distortion due to the limited quality of cameras, hide in the dark.

Philosophical Transactions
We present a brief introduction to the quantum theory of light as it is understood in the field of quantum optics. Our aim is not to review the topic, which would require a very extensive article (or even a book of several volumes) but rather to provide ...

We propose and verify a new concept of an all-optical transistor based on cross-phase modulation between a signal pulse (SP) and a control pulse (CP). An effective interaction is achieved if the CP is temporally locked to the SP in an optical event horizon.
