Analysis of Carrier Phase and Group Delay Biases Introduced by CRPA Hardware
Carrier Phase Group Delay Biases Introduced CRPA Hardware
2015/6/26
The benefits afforded by Controlled Reception Pattern Antennas (CRPAs) in multipath and interference mitigation are well documented, and they find use in many applications today. As such, CRPAs are be...
Experimental demonstration of two methods for controlling the group delay in a system with photonic-crystal resonators coupled to a waveguide
two methods controlling group delay system photonic-crystal resonators coupled waveguide
2011/8/10
We measure the group delay in an on-chip photonic-crystal device with two resonators side coupled to a waveguide.We demonstrate that such a group delay can be controlled by tuning either the propagati...
Real-Time Ultra-broadband Group Delay Monitoring through Quasi-Incoherent Processing
Fiber Bragg gratings Fiber optics communications Fiber optics components Bragg reflectors Dispersion compensation devices
2011/5/25
Simple method for real-time ultra-broadband group delay measurement of photonic devices is reported, demonstrating accurate group delay ripple monitoring of a 10m-long chirped fiber grating over the f...
Improvement of Chromatic Dispersion and Differential Group Delay Tolerance of Incoherent Multilevel Signaling with Receiver-side Digital Signal Processing
Fiber optics communications Modulation
2010/6/10
Chromatic dispersion and differential group delay tolerance of 30-Gbit/s 8DPSK and 8QAM signaling is investigated experimentally, and we show 1.7 and 1.25 times enhancement of them in 8QAM signaling b...

Suppression of Inter-Channel Nonlinearities in WDM Coherent PDM- QPSK Systems Using Periodic-Group-Delay Dispersion Compensators
Inter-Channel Nonlinearities WDM Coherent PDM- QPSK Systems Periodic-Group-Delay
2009/7/17
We show that periodic-group-delay dispersion compensators can significantly suppress inter-channel nonlinearities in a WDM coherent polarization-division-multiplexed quardrature-phase-shift-keying sys...
Suppression of XPM Penalty in Dispersion Managed Hybrid 10G/40G/100G DWDM Networks Using Group Delay Management
XPM Penalty Dispersion Managed Hybrid DWDM Networks Group Delay Management
2009/7/17
We propose a novel group delay management technique which effectively suppresses XPM accumulation in hybrid 10G/40G/100G DWDM networks. Systematic investigation reveals its high effectiveness for vari...
