Twisted light source

A compact source of laser light with a specific orbital angular momentum (OAM) state

The Bristol invention is a novel way of generating light with OAM in a low cost and very compact form that enables integration on a chip. Large arrays of emitters, with different OAM states, can for the first time be fabricated with potential applications in chip to chip interconnect technology and more complex optical manipulation schemes in biophysics. The emitter can be tuned on the chip to emit specific OAM states, and also has the potential to work in reverse to detect specific OAM states.
