Using Dispersion in a Fiber-Optic Loop to Perform Time Domain Analogue RF Signal Auto-Correlation
Using Dispersion Fiber-Optic Perform Time Domain Analogue RF Signal Auto-Correlation
2015/5/22
We present an RF-photonic time-domain auto-correlator using a dispersion-induced stepped-time-delay of the modulation sidebands produced by a fiber optic recirculation loop circuit. This allows spectr...
Fully Reconfigurable Compact RF Photonic Filters Using High-Q Silicon Microdisk Resonators
Integrated optics devices Wavelength filtering devices.
2015/5/21
We present a fully reconfigurable fourth-order SOI RF-photonic filter with a tunable bandwidth of 0.9–5 GHz, FSR > 600 GHz, out-of-band rejection > 38 dB, and compact size (0.15 mm 2 ) using high-Q re...

2015/5/21
We investigate the efficiency of RF-pilot based phase noise compensation for mitigation of nonlinear impairments in CO-OFDM transmission. We show that the efficiency scales with the effective dispersi...
Impact of RF Noise on Transmission Performance of Multiband OFDM UWB over Fiber Systems
RF Noise Multiband OFDM UWB over Fiber Systems Transmission Performance
2015/5/15
We investigate the performance of multiband OFDM ultra wideband (UWB) signal over fiber system considering the impact of RF noise. A compensation technique is proposed to reduce RF noise impact.
