Abstract :
A two-dimensional photonic crystal (2DPC) slab waveguide-based symmetric Mach-Zehnder type all-optical switch (PC-SMZ) is promising for a future ultra-fast photonic network system. An ultra-fast (~ps) and ultra-low energy (~100 fJ) switching has already been demonstrated as the 1st phase. The 2nd phase is to create a PC-SMZ-based ultra-fast photonic logical switch with a latch function for an ultra-fast photonic digital processor. One of the steps towards the goal is to develop a new design method of waveguides with wide/flat bandwidth, high transmittance and low reflectivity for improving switching performances. Another one is to develop a selective area growth of quantum dots. This paper dominantly reviews these two recent topics as well as briefing the PC-SMZ performances
