Thought for the month

“You cannot have freedom without a rule of law ... and if you don't have it, what you tend to get is corruption and that is death to freedom, it's death to truth, it's death to honour, it's death to democracy.”

Margaret Thatcher, 1 October 1996.

Optical link

Stanford engineers have designed and built a prism-like device that can split a beam of light and bend it at right angles a further step in their aim of developing nanophotonics and optical computing. The full paper is available here describing the optical link, a slice of silicon etched with a grating to split two different wavelengths of light at right angles separating O-band (1300 nm) and C-band (1550 nm) light into separate waveguides
