Optical Demultiplexing with Extinction Ratio Enhancement Based on Higher Order Parametric Interaction
Optical Demultiplexing Extinction Ratio Enhancement Based Higher Order Parametric Interaction
2015/7/14
We present the experimental demonstration of an all-optical demultiplexer for high speed OTDM data with optical regeneration capability. It is shown that higher order parametric interactions provide o...
A Novel Re-modulation Method in a WDM-PON with Enhanced Extinction Ratio
Method WDM-PON Extinction
2015/8/3
We propose and experimentally demonstrate a novel coding scheme for a WDM-PON system using ASK/DPSK re-modulation corresponding to downstream/upstream signals respectively to enhance the toleration of...
Sensitivity of Interferometric OSNR Measurements Techniques to the Variation in Signal Extinction Ratio
Sensitivity Interferometric OSNR Measurements Techniques Variation Signal Extinction Ratio
2015/7/31
We discuss calibration requirements for interferometric OSNR measurements. We show that variation of 0.25dB in the signal extinction ratio could result in large errors in OSNR for 42.8Gb/s modulated s...
