The development of a system facilitating the convergence of millimeter-wave and optical systems is highly desirable to realize 5G/beyond 5G mobile communication. However, such broad-bandwidth signals cannot be easily transmitted using a long optical fiber owing to the optical fiber chromatic dispersion effect. This paper reports upon the realization of a high-speed millimeter-wave radio-over-fiber signal transmission by using an optical single-sideband (SSB) modulation scheme. The combination of an optical intensity modulator and optical filter can provide the optical SSB signals with an automatic bias controller. The IEEE802.11ad-compliant packet streams are successfully transmitted and converted into 105 GHz millimeter-wave signals. The system can generate and transmit a packet in 16-QAM under an error vector magnitude of 4.8% at a frequency of 104.77 GHz.

This Letter proposes a high-performance radio-over-fiber (RoF) system for high-speed and high-fidelity analog waveform transmission of radio signals in the millimeter-wave band in the uplink direction. At the antenna site, the system utilizes a newly fabricated low half-wave voltage broadband phase modulator to convert a millimeter-wave radio signal into an optical signal. At the receiver, by using photonic downconversion and optical filtering technology, a simple direct detection and downconversion of the signal to the microwave band can be achieved simultaneously. As a demonstration of proof of concept, we successfully transmitted a 1024-quadrature amplitude modulation (QAM ) narrowband orthogonal frequency-division multiplexing signal at 38 GHz and a 60 Gb/s 64-QAM single-carrier signal at 26.5 GHz over a 20 km RoF system. The system is promising for facilitating the deployment of ultra-dense small cells in high-frequency bands in 5G and beyond networks. (C) 2021 Optical Society of America

We report the development of a superconducting acousto-optic phase modulator fabricated on a lithium niobate substrate. A titanium-diffused optical waveguide is placed in a surface acoustic wave resonator, where the electrodes for mirrors and an interdigitated transducer are made of a superconducting niobium titanium nitride thin film. The device performance is evaluated as a substitute for the current electro-optic modulators, with the same fiber coupling scheme and comparable device size. Operating the device at a cryogenic temperature (T = 8 K), we observe the length-half-wave-voltage (length-V-pi) product of 1.78 V.cm. Numerical simulation is conducted to reproduce and extrapolate the performance of the device. An optical cavity with mirror coating on the input/output facets of the optical waveguide is tested for further enhancement of the modulation efficiency. A simple extension of the current device is estimated to achieve an efficient modulation with V-pi = 0.27 V.

High data rates and low latencies will be indispensable in next generation communication devices. In order to achieve these targets, the use of wireless communication technology combined with photonics and optics is expected to have significant potential. In this paper, we present a key device for advanced fiber wireless and optical wireless communications. A new device integrated with a 100 GHz uni-travelling carrier photodetector and a 100 GHz pHEMT amplifier is introduced for high data rate fiber wireless communication applications operating at data rates above 20 Gbps. For optical wireless communication applications, another novel two-dimensional photodetector array (2D-PDA) device is introduced, and demonstrated for 100 Gbps high data rate communications using the wavelength division multiplexing (WDM) technology in free-space.
