Development of a Lumped Constant Type Optical Modulator in the Microwave Band for Digital Terrestrial TV Broadcasting

摘要：

This article describes development and construction ofan evolutional lumped constant type LiNbO3 optical modulatorthat operates via a faint signal in the microwave frequencies forTV program transmission of terrestrial digital TV broadcastingwith a bandwidth of 6-9MHz. This modulator modulates a lightbeam at 1.5 μ m with OFDM (Orthogonal Frequency DivisionMultiplex) signals at a 6-7GHz band and a voltage level of 60dB μ Vfrom a receiving antenna. Performance was satisfactory.
