2009/7/16
10.3Gb/s burst-mode 3R receiver incorporating full AGC optical receiver and 82.5GS/s sampling CDR for 10G-EPON is, for the first time, developed. Burst receiver sensitivity of -30.1dBm and upstream po...
This paper discusses how commercial 40 Gb/s transponders can be used for upgrades of medium haul submarine links by taking into account dispersion optimisation requirements and co-existing channels.
Tomography for Multiconjugate Adaptive Optics Systems Using Laser Guide Stars
Adaptive Optics Laser Guide Stars Tomography Algorithms
2004/6/1
In this paper we present a solution to the MCAO reconstruction problem using multiple laser guide stars and show that it can be interpreted as a form of back-projection tomography. It is shown that a ...
