Periodic and Quasi-Periodic Compensation Strategies of Extreme Outages caused by Polarization Mode Dispersion and Amplifier Noise

Effect of birefringent disorder on the Bit Error Rate (BER) in an optical fiber telecommunication system subject to amplifier noise may lead to extreme outages, related to anomalously large values of BER. We analyze the Probability Distribution Function (PDF) of BER for various strategies of Polarization Mode Dispersion (PMD) compensation. A compensation method is proposed that is capable of more efficient extreme outages suppression, which leads to substantial improvement of the fiber system performance.Comment: 3 pages, 1 figure, Submitted to IEEE Photonics Letter

Strong birefringence at 1.55 µm of single-mode TE00 and TM00 rib optical waveguides composed multi-quantum-well structures

International audienceThe authors have designed, fabricated and characterised singlemode rib optical waveguides at 1.55 µm with high form birefringence. The core of the waveguide, which is composed of alternate layers of GaAs and AlAs, propagates both TE00 and TM00 modes with good vertical and lateral confinement, and presents a modal birefringence of >0.047 at 1.55 µm. This is an essential step for the conception of acousto and optoelectronic components on multiquantum well structures
