Experimental Comparison of Performance Monitoring Using Neural Networks Trained with Parameters Derived from Delay-Tap Plots and Eye Diagrams
Fiber optics communications Pattern recognition neural networks
2015/6/4
We experimentally demonstrate the use of artificial neural networks trained with parameters derived from both delay-tap plots and eye diagrams for multi-impairment monitoring in a 40-Gbit/s non-return...
Clear eye opening 1.3μm-25 / 43Gbps EML with novel tensile-strained asymmetric QW absorption layer
tensile-strained asymmetric QW absorption layer
2015/7/16
We demonstrate 1.3μm-25/43Gbps EML with novel tensile-strained asymmetric quantum well absorption layer. Clear eye opening was achieved under high output power condition (>+5dBm) both before / after 1...
A theoretical model of the human eye based on ultrasound and corneal data
biometry theoretical eye model lens
2011/5/6
The purpose of this study was to create a theoretical model of the eye based on a comparison of the real spherical equivalent of the eye and the calculated value of the axial refraction. The main cont...
