We present an overview of the recent developments in nonlinear silicon photonics. There were significant advances in devices exploiting the ð2Þ and ð3Þ nonlinearities. Here, we discuss parametric amplification, wavelength conversion, supercontinuum generation, parametric oscillation, and frequency comb generation in siliconbased devices.

In order to avoid laser-induced damage to optical components during amplification of a short laser pulse, the pulse often is first stretched in time to reduce its peak power, amplified, and then recompressed. High peak irradiance is attained when the laser beam is subsequently focused onto a laser fusion target. In a laser system, currently under construction, large diffraction gratings will be...

We report the observation of more than 7 dB of vacuum squeezing from a below-threshold optical parametric oscillator (OPO). We discuss design criteria and experimental considerations for its optimization and demonstrate that the vacuum squeezing can be electro-optically transferred to a bright beam using a feed-forward loop. This is compared with the bright intensity squeezed beam generated by ...

This paper demonstrates a method to remove the gain ripple profile specifically for a two-segment fiber optical parametric amplifier arising from the dispersion differences between the fiber gain medium and the standard single mode fiber attached to the optical components. This is achieved by using a simple design that incorporates a gain smoothening filter at the mid-stage of the amplifier. Th...

Bézier surfaces have been widely employed in the designing of complex scenes with high-quality results. Nevertheless, parametric surfaces cannot be directly rendered in the current GPUs of modern handheld devices. This work proposes a non-adaptive method for tessellating Bézier surfaces on a GPU without primitive generator, such as the GPUs implemented in handled devices. Our technique is based...
