Simultaneous Improvements of Gain and Linearity in Dispersion-Tolerant Phase-Modulated Analog Photonic Link
Published 2017-01-01Get full textA high-gain, dispersion-tolerant, and linear phase-modulated analog photonic link is proposed and demonstrated based on full spectrum optical sideband processing (FSOSP). In the proposed link, upper sidebands and lower sidebands are transmitted separately in different optical paths. By suppressing t...

Passive-Compensation-Based Stable RF Phase Dissemination for Multiaccess Trunk Fiber Link With Anti-GVD and Anti-Backscattering Function
Published 2017-01-01Get full textWe propose and demonstrate a scheme of stable radio frequency (RF) phase dissemination for multiaccess trunk fiber link by passive frequency mixing with anti-group velocity dispersion (GVD) and anti-backscattering function. The propagation delay of the entire fiber link is detected by a round-trip p...

Broadband Spurious-Free Dynamic Range Expander for Microwave Photonic Links Based on Optical Distortion Control
Published 2019-01-01Get full textA wideband spurious-free dynamic range (SFDR) expander that uses optical distortion control technique is proposed in this study for microwave photonic links. A third-order intermodulation distortion (IMD3), which is sensed by extracting the modulated optical carrier, will be monitored and attenuated...

A Novel High-Linearity Microwave Photonic Link Based on the Strategy of Adding a Compensation Path Using a Bidirectional Phase Modulator
Published 2016-01-01Get full textA novel phase-modulation direct-demodulation microwave photonic link for improving the spurious-free dynamic range (SFDR) is proposed and experimentally demonstrated. In the proposed system, two different C-band optical wavelengths are modulated by a phase modulator in opposite directions. After com...
