Coherent optical effects Heterodyne Interferometry
2015/5/25
Faraday rotator mirrors in a Michelson interferometer configuration is shown to significantly improve resolution and coherence for delayed self-heterodyne interferometery.Coherence is clearly observed...
Optical Carrier Suppression and Balanced Coherent Heterodyne Detection for Improved Performance in Wide-band Microwave Photonic Links
Optical Carrier Suppression Balanced Coherent Heterodyne Detection Improved Performance Wide-band Microwave Photonic Links
2015/6/8
We demonstrate a wide-band microwave photonic link with high gain and dynamic range, low noise figure, and dispersion-free propagation using double sideband suppressed carrier modulation, optical ampl...
Phase Stable RF-over-fiber Transmission using Heterodyne Interferometry
Radio frequency photonics Fiber optic links subsystems
2015/6/4
We demonstrate stable transmission of 3GHz over 300m of fiber with less than 0.017 degree (17fs) RMS phase error. An interferometer measures optical phase delay, providing information to a feed-forwar...
Experimental Demonstration on the Reduction of Linewidth Impact in a Self-Heterodyne Optical OFDM System
Fiber optics communications Modulation
2015/6/4
We show experimentally that the signal quality of a self-heterodyne optical OFDM system can be improved by temporally realigning the carrier with the subcarriers before photodetection. This can be exp...
