Self-steepening of ultrashort pulses in silicon photonic nanowires.
947 - 949.
We study the frequency dependence of the optical nonlinearity of Si photonic nanowires (Si-PNWs) and its influence on the propagation of ultrashort optical pulses in such nanodevices. Specifically, we show that Si-PNWs present a remarkably large characteristic time associated with self-steepening effects and optical shock formation, namely, more than an order of magnitude larger than in the case of photonic crystal fibers.
