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.
300-GHz multilevel signal transmission over optical fibers and air is demonstrated using advanced optical communication technology including optical frequency comb generation. Local oscillator signal transport over optical fibers to optical-terahertz converters removes the need for setting any terahertz-capable oscillators in the converters. This fiber-remoted configuration with seamless conversion...
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.
