Second-Order PMD Monitoring from Adaptive FIR-Filter Tap Coefficients in a Digital Coherent Receiver
Fiber optic communication Coherent communications Homodyning
2015/5/26
We propose a straightforward algorithm to estimate second-order PMD from adaptive FIR-filter tap coefficients in a digital coherent optical receiver. The novel algorithm is verified with 100-Gbit/s du...

Novel Theoretical Procedure Determine Absorption Gain Coefficients Symmetric Single Step-Index Quantum Well Laser
2009/7/28
If the indices nII, nI,III of the regions, the thickness 2a of the active region (AR) and the wavelength l for a single symmetric step-index quantum well laser (SSSIQWL) are given, the normalized prop...
For the first time to our knowledge the computation of the expansion coefficients of the principal modes of multimode fibers is reported.
