Yep, word is that this is the smallest map ever made!
The scale is 1: 1 trillionth !
The map was created by manipulating light on a submicrometer scale in tiny strips of silicon called waveguides or photonic wires. The different colours are caused by interference effects in the different layer thicknesses of silicon. These silicon photonic circuits can pack a million times more components on the same footprint as today’s commercial glass-based photonics.Just a thought: If you intend to use this map as the base layer on a PDA you might want to upgrade to a bloody sharp pointer-pen to navigate around it!
