Fiber-Optic Event Horizon Mimics Black Hole [Slideshow]

Researchers hope to detect faint radiation emanating from a new laboratory version of a black hole event horizon

MAKE YOUR OWN WHITE HOLE

Simulating the event horizon of a white holean insideout black hole that permits no light to enteris as simple as letting water from the tap pour onto a flat surface, as shown here. Inside the ring of water waves is the so-called hydraulic jump, a smooth area where water moves faster than the speed of the waves, hence no waves can enter this region.....[ More ]

HAWKING RADIATION

Hawking Radiation is the faint glow theorized by physicist Stephen Hawking to stream from a black hole due to pair creation, the simultaneous birth of twin particles of light, near the event horizon. ....[ More ]

"FERRARI LASER"

To have any hope of detecting faint radiation emanating from an analog of a black hole event horizon in a new laser-based method, researchers will have to create short, high-intensity laser pulses shaped like a shark fin.....[ More ]

PRISM

The supercontinuum output of the microstructured fiber dispersed by the prism (right) onto the screen (left). The prism separates the colors of light.....[ More ]

OVER THE HORIZON

Experimental setup for measuring the shortening, or blue-shifting, of an infrared beam's wavelength at an event horizon in a spool of optical fiber (blue circle added for clarity). Colored lines show the paths of incoming laser pulses (red), the infrared probe light (green) and a beam for probing the mixture of the two (magenta).....[ More ]

SUPERCONTINUUM SPECTRUM

Detail of the broad spectrum, or supercontinuum, light output from a microstructured fiber used to create an analog of a black hole's event horizon. Dispersed by a prism and projected onto the screen, the light contains the full rainbow.....[ More ]

EVENT HORIZON

Researchers have reproduced an event horizon similar in principle to ones found around black holes by shining laser pulses down a microstructured, or microscopically patterned, optical fiber, shown here.....[ More ]
