A completely new design for an all‐silicon all‐optical pass switch has been proposed based on the stimulated Raman scattering (SRS) in silicon nanocrystal embedded slotted photonic crystal waveguide (SPCW). Substantial miniaturisation in the device footprint and operating power has been attained by merging the benefits of the giant SRS gain and the ultra‐high optical confinement of the SPCW. The proposed switch offers a tremendously high contrast ratio of ∼ 27dB between the logic levels and an extraordinary bit rate of 125 Gbps.
