Performance Comparison of Photonic Downconversion for Uplink Mobile Fronthaul

Pham Tien Dat, Yuya Yamaguchi, Atsushi Kanno

IEEE Photonics Technology Letters 34 ( 17 ) 923 - 926 2022年09月

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：Institute of Electrical and Electronics Engineers ({IEEE})

This study compares the performance of photonic downconversion technology using single and dual wavelength modulation methods using an optical phase modulator. We compared the system characteristics, including the conversion gain, phase noise, and spurious-free dynamic range, of the two approaches. To demonstrate the proof-of-concept, we transmitted high-order quadrature amplitude modulation orthogonal frequency-division multiplexing signals in the 43 and 52 GHz bands over the system. The results confirm the potential of the system as a promising solution for uplink mobile fronthaul in high-frequency bands, such as in 5G-Advanced networks.

A Mach-Zehnder optical modulator with the tunable multimode interference coupler was fabricated using Ti-diffused LiNbO3. The modulation extinction ratio could be voltage controlled to maximize up to 50 dB by tuning the coupler. Optical single-sideband modulation was also achieved with a sideband suppression ratio of more than 30 dB.

Abstract
Random signal generation in a ring resonator laser is achieved with quantum-dot semiconductor optical amplifiers. The lasing spectra were obtained over a wide range of wavelengths, and the individual longitudinal modes acted as the channels for random number generation.

Transparent Fiber-Millimeter-Wave-Fiber System in 100-GHz Band Using Optical Modulator and Photonic Down-Conversion

Dat, P.T., Yamaguchi, Y., Motoya, M., Oikawa, S., Ichikawa, J., Kanno, A., Yamamoto, N., Kawanishi, T.

Journal of Lightwave Technology 40 ( 5 ) 1483 - 1493 2022年

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：Institute of Electrical and Electronics Engineers ({IEEE})

We demonstrate the first fiber-millimeter-wave-fiber system in the 100-GHz band using a low-loss optical modulator and direct photonic down-conversion technology. The utilization of a low-loss optical modulator for the direct conversion of a millimeter-wave signal to an optical signal significantly simplifies the millimeter-wave radio receiver because it includes only a radio front-end and an optical modulator. In addition, by adopting direct photonic down-conversion technology for simultaneous detection and down-conversion of the millimeter-wave signal to the microwave band, the fiber-radio receiver and subsequent digital signal processing can be considerably simplified. Using the proposed technologies, we successfully transmitted 32-/64-quadrature amplitude modulation orthogonal frequency division multiplexing and single-carrier signal with a line rate of 71.4 Gb/s and a net data rate of 53.7 Gb/s over a wired and wireless converged system consisting of two optical fiber links and a 20 m radio link at 101 GHz. The proposed system is promising for high-capacity, low-latency, and low-power consumption fiber-wireless transmission in beyond 5G networks.
