Cross-phase modulation (XPM) changes the state-of-polarization (SOP) of the channels that leads to amplitude modulation of the propagating waves in a WDM system. Due to the presence of polarization mode dispersion (PMD), the angles between the SOP of the channels change randomly and the modulation amplitude fluctuation in the perturbed channel becomes random. We analytically derive the dynamic equation...
In this paper, our recent work interval-based orderly scheduling strategy (IOSS) is extended by adding quality-of-service (QoS) provisioning. A revised medium access control (MAC) protocol is introduced, which supports priority-based QoS in wavelength division multiplexing (WDM) networks with star topology. The proposed interval-based prioritized orderly scheduling strategy (IPOSS) operates in a distributed...
We designed an innovative frequency multiplexer based on contra-directional coupling and standing-wave resonators within a photonic crystal (PhC) structure. Three add-drop filters were cascaded, and the lattice periods of the PhC strips containing the cavities were changed to tune the dropped frequencies, with a very high degree of freedom. Each filter has a 1 nm bandwidth around 1550 nm and the three...
