Creating Horizons for Light using Metamaterials

Professor Thomas Philbin

Information, and Photonics in Erlangen

Abstract:   Photonic crystal fibres are metamaterials that offer remarkable control of nonlinearity, birefringence and dispersion. We describe how ultrashort pulses in photonic crystal fibres create artificial event horizons for probe light, analogues of the event horizon of a black hole. We have experimentally observed an expected classical effect: the blue-shifting of the probe light at a white-hole horizon. Such a system can also be used to investigate the quantum effects of horizons, in particular Hawking radiation.
