State-of-the-Art Photonic Crystal Fiber

William Wadsworth, Jonathan Knight and Tim Birks

Photonic crystal fibers (PCFs) can change the way light is generated, delivered and used. Supercontinuum generation, four-wave mixing and hollow-core PCF technology may enable breakthroughs in science—especially in medicine and microscopy.


Breaking the Tbit/s Barrier: Higher Bandwidth Optical Processing

The growing demand for broadband communications has inspired many approaches to increasing capacity. Our recent work shows that combining linear and nonlinear optical signal processing can overcome some of the challenges faced by high-symbol rate signals.

Global Trends in Optical Manufacturing

After the telecom bubble burst in 2002, many North American optical companies outsourced production to Asia on a grand scale. A decade later, the global industry is rebalancing itself in interesting ways.

Changing the Lights: Are LEDs Ready to Become the Market Standard?

Solid-state lighting promises higher efficiency than fluorescent or incandescent bulbs—and without their many limitations. Yet the bright new technology faces important challenges before it can truly replace Thomas Edison’s venerable invention.
