Time variation of refractive index in the core of active fiber under pulsed optical pumping
Time variation refractive index active fiber pulsed optical pumping
2015/8/4
The kinetics of refractive index change in active fiber under pulsed cladding-coupled optical pumping was investigated using interferometric technique. Relaxation processes after lasing threshold was ...
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...
