Fiber-wireless transmission in the terahertz-wave band as well as in the millimeter-wave band is the key for a seamless integration of radio and optical networks in a physical layer. Advanced optical fiber communication technology enables a high precision direct waveform transfer between optical and radio domains. For realization of a seamless conversion, an optical-terahertz converter is configured...
This paper presents the simultaneous transmission of millimeter-wave and terahertz-wave radio signals over an optical fiber and air by a single optical frequency comb source with several types of receiver configurations.
We demonstrate W-band (75–110 GHz) RoF radio signal transmission with two free-running lasers using an optical heterodyne technique. The combination of a laser located at a base station for the optical local oscillator and a data-modulated optical signal from a central office provides a W-band radio signal. The carrier frequency offset fluctuation within 6 MHz can be mitigated by digital signal processing...
40-Gb/s W-band 16-QAM radio-over-fiber signal is optically synthesized using dual-polarization QPSK modulator. Its wireless transmission within FEC limit is demonstrated with optical self-heterodyne detection and digital signal processing.
