Photonic Crystals and Quantum Dots: Towards Integrated Optics for Advanced Ultra-Fast All-Optical Signal Processing

Nano-photonic technologies of GaAs-based two-dimensional photonic crystal (2DPC) slab waveguides and InAs-based quantum dots (QDs) are reviewed for a symmetric Mach-Zehnder type, ultra-small and ultra-fast all-optical switch (PC-SMZ) and new logic (PC-FF) device.
