OT: Breakthrough in nonlinear optics research

"...This nonlinear scattering process can cause signal distortions in fibre communications and signal processing applications and is well known to limit the capacity of optical fiber communications networks....
...To address this, the researchers introduced a grating structure on to the chip. The grating, which comprises a small modulation in the optical material properties, forms a bandgap for light, which strongly effects the propagation of light, in the same way that semiconductors control the flow of electrons. When the laser wavelength is tuned close to the edge of the bandgap, the speed of light is reduced. This will greatly enhance the optical nonlinearity. At a slightly different frequency, the bandgap will completely inhibit (or suppress) the optical nonlinearity. The grating can be tuned so that the optical nonlinearity can be turned on and off on-demand."
