Key Technologies of WDM-PON for Future Converged Optical Broadband Access Networks [Invited]
Gee-Kung Chang,Arshad Chowdhury,Zhensheng Jia,Hung-Chang Chien,Ming-Fang Huang,Jianjun Yu,Georgios Ellinas +6 more
TL;DR: In this paper, the authors proposed a converged WDM-PON architecture for longer reach, higher data rate, and higher spectral efficiency for single-source systems and integrated the integrated schemes with radio-over-fiber (RoF)-based optical-wireless access systems to serve both fixed and mobile users in the converged optical platform.
Journal ArticleDOI
Cost-Effective Optical Millimeter Technologies and Field Demonstrations for Very High Throughput Wireless-Over-Fiber Access Systems
Jianjun Yu,Gee-Kung Chang,Zhensheng Jia,Arshad Chowdhury,Ming-Fang Huang,Hung-Chang Chien,Yu-Ting Hsueh,Wei Jian,Cheng Liu,Ze Dong +9 more
TL;DR: In this article, several key enabling technologies for very high throughput wireless-over-fiber networks are reviewed, including photonic mm-wave generation based on external modulation or nonlinear effects, spectrum-efficient multicarrier orthogonal frequency-division multiplexing and single-carrier multilevel signal modulation.
Journal ArticleDOI
Tunable S-band erbium-doped triple-ring laser with single-longitudinal-mode operation.
TL;DR: A tunable and stable single-longitudinal-mode (SLM) erbium fiber laser with a passive triple-ring cavity structure in S-band operation with performances of the output power, wavelength stability, tuning range, and side-mode suppression ratio (SMSR) are studied.
Journal ArticleDOI
Advanced System Technologies and Field Demonstration for In-Building Optical-Wireless Network With Integrated Broadband Services
TL;DR: In this article, an intelligent gateway router (IGR) is proposed as a unified platform to accommodate multi-gigabit, millimeter-wave services at 60GHz band as well as being backward compatible with all current wireless access technologies such as WiFi and WiMAX.
Journal ArticleDOI
Multiband Signal Generation and Dispersion-Tolerant Transmission Based on Photonic Frequency Tripling Technology for 60-GHz Radio-Over-Fiber Systems
Zhensheng Jia,Jianjun Yu,Yu-Ting Hsueh,Arshad Chowdhury,Hung-Chang Chien,John A. Buck,Gee-Kung Chang +6 more
TL;DR: In this paper, an efficient photonic frequency-tripling technology for 60 GHz radio-over-fiber systems to simultaneously realize millimeter-wave (mm-wave), microwave, and baseband signal generation was designed and experimentally demonstrated.
