Optical Design & Engineering
Quantum-like polarization metrology with classical light
Light beams with nonuniform polarization patterns with the same properties as entangled quantum systems can perform tasks that are commonly believed impossible in classical optics.
First solid-state cooling below 100K
Advances in material purity and laser light absorption offer new possibilities for vibration-free cryogenic cooling.
Screen-free display formed using retro-reflector
An aerial display on which signage pops up has been realized using retro-reflective sheeting, an LED panel, and a half mirror.
Fabricating tools for optically actuated microrobotics
Using focused light beams to suspend and autonomously control microscopic tools in 3D enables novel ways to investigate the microscale world.
Increasing light-induced forces with photonic crystals
A new structure of free-standing 1D porous silicon foils is configured to produce forces that are 500 times greater than conventional optical tweezers.
