Single-Crystal, Organic Nanowire High-Performance Phototransistors
The photoelectronic characteristics of high-performance phototransistors based on single-crystalline n-hannel organic nanowires are studied.
More signal less noise: inproved nonlinear optical imaging
A superior signal to noise ratio for heterodyne detected nonlinear optical imaging can be attained by a newly developed tuned amplifier system in a lock-in free manner, as demonstrated through stimulated Raman scattering imaging of live cells and tissues.
Detection of Explosives: An All-in-Fiber Chemical Sensor for Peroxide Vapors
Scientists report a new method for remote tracing of vapors escaping from the liquid-peroxide explosives used in terror bombing incidents.
Highly Unidirectional Emission from Ultrahigh-Q Microcavities
A new type of on-chip microcavities has been realized, which features both highly unidirectional emission and ultra-high-Q factors in the near infrared.
Quantum optics wins researchers Nobel Prize in Physics for 2012
David Wineland and Serge Haroche win award from work on light-matter interaction.
Towards Quantum Dot Lasers with Temperature Independent Threshold
Carefully engineered CdSe/CdS colloidal quantum dots show an almost constant amplified spontaneous emission threshold over a temperature range from 5–325 K.
A model for chiral polymer synthesis
The synthesis of a chiral polymer can be performed in chiral liquid crystals. It could be a model to understand asymmetric polymer synthesis in biology.
Unconventional laser beams are in good shape
Aside from the classical Gaussian intensity profiles, unconventional laser beam shapes open up new perspectives for technologically relevant areas such as deep-hole drilling, photopolymerization, and nanopatterning.
Near-Field Enhancements along Ring-Shaped Nanostructures
