Abstract
In this work, we introduce the periodic wavelength arrangement, which is similar to the cyclic filtering and free spectral range characteristic of arrayed waveguide grating in to the design of all optical packet switch and fiber Bragg grating sensor network. In all optical packet switch: We conceptually propose and experimentally demonstrate several novel optical packet switch, include buffer decomposition algorithm based all optical packet switch, wideband fiber Bragg grating based all optical packet switch, and configurable all optical packet switch. Moreover, in the fiber based sensing system, we also propose and demonstrate three dimensional mesh based sensing and three dimensional ring topology base sensing system, in which, comprehensive self-healing functionality and routing algorithm are also been implemented.
