New Suite of Femtosecond Lasers Lowers Costs and Complexity of Microscopy

Single-layer OLED design could dramatically reduce display costs

When illuminated with laser light, a liquid-crystal elastomer robot (inset) about 1 cm long crawls up walls and across ceilings just like the banded snail sitting next to it.

Light-activated LC elastomer propels biomimetic “snail robot”

$Operation principles of a differential diffractive optical neural network. Since diffractive optical neural networks operate using coherent illumination, phase and/or amplitude channels of the input plane can be used to represent information.$
