Bursts with 212 – 1 and 216 – 1 pseudo random binary sequence (PRBS) were studied, with different idle times. The use of traffic with variable idle time was assessed in order to evaluate the effect on the burst initial amplitude. We also analyzed the performance of the packet based system by measuring the Q factor at the receiver and concluded that the performance is not affected by the type of traffic (variable or fixed idle times)

Erbium doped organic compounds for integrated optics.

In this paper, optical properties of novel 1.54 μm emitting organic compounds are presented. Erbium tris (8-hydroxyquinoline) and Erbium dibromo-quinoline thin films have been solution processed and are compared by absorbance and infrared emission. Edges and flaws related to the processing of the two compounds are remarked. © 2008 IEEE

Stable oscillating nonlinear beams in square-wave-biased-photorefractives

Summary form only given. Optical micrometer sized beams in biased photorefractives self-trap in a transient regime, reaching steady-state by increasing the sample conductivity. We investigate a fundamentally different stabilization process connected to beam behaviour in a non-stationary external bias field. We study beam evolution in the presence of an alternating field in centrosymmetric potassium-lithium-tantalate-niobate (KLTN

Applications and Low Cost Processing of Erbium Quinolinolates for Active Integrated Photonic Devices

Rare earth-doped organic materials represent a promising alternative to play the role of active materials for Photonic Integrated Circuits (PICs), meeting the requirement of low cost integration. In particular, Erbium Quinolinolates (ErQ) attracted a strong interest in the last decade for their good efficiency of emission in the C band of the optical communications centered at 1550 nm. In this paper, a resume of the application of ErQ for processing of photonic devices is presented. Results deriving from the optical characterization of the ErQ materials and their application as active materials into optical waveguides and light emitting devices are reported. Finally, the results of the improvement of the ErQs via a purposed chemical synthesis towards more efficient and lower cost solution processed devices are presented
