Fast SOP Variation Measurement on WDM Systems Are the OPMDC Fast Enough?
Fast SOP Variation Measurement WDM Systems Are OPMDC
2015/7/16
Orange Labs organized a 6 month field trial to characterize states of polarization (SOP) variations with time on representative links of the future 40 Gbit/s deployment and to enable specifying the ad...
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...
Phase variation of fundamental field induced by cascaded second order nonlinear processes in KTP
induced phase variation cascaded second-order processes the fundamental field
2011/4/26
In this paper it has been demonstrated by numerical simulation that the intense second harmonic field induces a nonlinear phase change on a fundamental field simultaneously through the cascaded second...
