Penn Researchers Develop Liquid-crystal-based Compound Lenses That Work Like Insect Eyes
Penn Researchers Liquid-crystal-based Compound Lenses Work Like Insect Eyes
2015/5/25
The compound eyes found in insects and some sea creatures are marvels of evolution. There, thousands of lenses work together to provide sophisticated information without the need for a sophisticated b...
SPIE wins BNA for design work on Prism Awards for Photonics Innovation（图）
SPIE BNAs -- design competition Photonics Innovation
2011/4/21
SPIE is among the winners named recently in the inaugural Brand New Awards -- BNAs -- design competition, for identity work done surrounding the Prism Awards for Photonics Innovation.
A new optical fiber line testing function for service construction work that checks for optical filters below an optical splitter in a PON
Fiber measurements Fiber Bragg gratings
2015/6/5
We propose a new function for construction-work undertaken to install optical cables for services in PONs. We demonstrated to determine whether an optical fiber is “live” or “unused”in branched fiber-...
Why Traffic Engineering Does Not Work for Physical Impairments Based Routing
Traffic Engineering Does Physical Impairments Routing
2015/7/17
ln all optical routing the main question is the permissible distance. Signal power is a key resource. The most common idea of resource balancing is Traffic Engineering. We will show with examples and ...

A way to the engineering of the quantum states of trapped ions – report of work in progress
Paul trap nonlinear resonances
2011/5/3
We studied the influence of geometry on the interaction of ions in a Paul trap with microwave radiation and the spatial velocity distribution from the Doppler shift. Non-linear resonances in a Paul tr...
