We have experimentally demonstrated two-dimensional (2D) photonic crystal (PC) waveguides (WG) necessary for a 2D PC-based symmetric Mach-Zehnder (PC-SMZ) type ultrafast all-optical switch such as straight WG, bent, Y-branch, directional coupler (DC) and quantum dots (QD)-based optical nonlinear (ONL) WG, using a GaAs air-bridge membrane with triangular-lattice line-defect WG. Experimental results on the successful optical interference at the Y-junction DC, nonlinearity-induced phase shift at the ONL waveguide, and transmission spectra in the total PC-SMZ WG configuration are addressed as well as measured results on each WG element.
