Optical Heterodyne Millimeter-Wave Analog Radio-over-Fiber with Photonic Integrated Tunable Lasers

Optical Fiber Communication Conference (OFC) 2019, 2019
Analog radio-over-fiber links enforce strict laser requirements for optical heterodyne systems. Experimental results show the successful implementation of two free-running, uncorrected micro-ring resonator based tunable lasers in a 60GHz A-RoF heterodyne system over 25km.

Complexity-reduced analog predistortion using schottky diode for radio-over-fiber systems

2014 12th International Conference on Optical Internet 2014 (COIN), 2014
In this paper, we propose a novel and simple predistortion method using schottky diode to compensate the nonlinear characteristics of the DFB-LD for RoF systems. The experimental results show that the enhancement of about 30 dB in the third-order intermodulation distortion (IMD3) and about 10 dB in the spurious-free dynamic range (SFDR) are achieved at

Radio over Fiber : DWDM Analog/digital Access Network and its Enabling Technologies

LEOS 2007 - IEEE Lasers and Electro-Optics Society Annual Meeting Conference Proceedings, 2007
Dense WDM access network which allows to co-exists analog radio over fiber and digital FTTH systems is investigated. Focuses are on the enabling techniques such as optical frequency interleaved DWDM grid assignment, supercontinuum light source, multi-band RoF and digital signals transmission, and optical path routing for dynamic channel allocation for ...
