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. |
