This week CIAN hosts two University of Southern California students, speaking about their research.
Ahmed Almaiman –
…is a graduate student in the University of Southern California. He joined the optical communications group led by prof. Alan Willner in 2012. Since then, Ahmed has been working on optical performance monitoring and optical nonlinear systems.
We demonstrate an optical-signal-to-noise-ratio (OSNR) monitoring scheme of 200-Gbit/s PM-16QAM and 100-Gbit/s QPSK signals using Mach-Zehnder delay-line-interferometer with <0.5 dB error for signals with up to 22 dB actual OSNR. We also determine design guidelines to achieve a desired level of accuracy.
Amirhossein Mohajerin Ariaei –
…is a graduate student at University of Southern California (USC). He joined the optical communications Laboratory (OC Lab) led by prof. Alan Willner in 2012. Since then, Amirhossein has been working on optical signal processing, and optical communication systems
We demonstrate the generation of optical 16-QAM and 64-QAM at EVM 6.8% and 6.4% respectively using nonlinearities and coherent frequency comb. We also demonstrated a successful transmission through 80-km SMF-28 after compensating with 20-km DCF with negligible penalty.
