Dynamic switching characteristics in waveguide-type collinear acoustooptic (AO) devices are investigated for applications to wavelength-selective matrix switches and routers in wavelength-division-multiplexing (WDM) photonic networks. The device has the feature of simultaneous controllability for multiple wavelengths over a range of more than 100 nm. Experimental studies on optical filtering have been investigated. In order to find the optimum high-effciency design of a compact integrated optical wave separator, the dynamic characteristics of photonic switching of optical signals by AO interaction are studied numerically using the finite-difference-time-domain (FDTD) method. The analytical model consists of slab-type symmetric directionally coupled waveguides formed on a LiNbO3 substrate. Wavelength-selective switching was numerically simulated and compared with the analysis using the coupled mode theory. A segmented FDTD method for simulating long optical devices with waveguides longer than 1 mm is also discussed.
