Abstract

In this paper, we have proposed sideband injection locking method, heterodyne technique, to generate millimeter-wave signal. Microwave signals in cellular broadband mobile communication networks and distributed networks can favorably be generated and distributed by optical techniques. In principle, these techniques have already been investigated for optical control of phase-array antennas, characterization of photo-detector and phase locking of millimeter-wave oscillators and now being applied to wireless communications. The generation and transmission of millimeter-wave radio signals by optical means is of interest for future pico-cell broadband mobile communication system, especially for systems operating at frequencies of tens of GHz applicable to LMDS. We experimented and analysed the generation of millimeter wave signal.

본 논문에서는 밀리미터파 대역의 신호 발생을 위한 헤테로다인 방식인 sideband injection locking 방법을 제안하고 실험적으로 분석하였다. 향후, 무선 이동통신, 초고속 광대역 통신망 등에 사용되어질 밀리미터파 신호는 전기적 요소의 한계로 광학적인 요소에 의해 신호를 생성하는 방법이 많이 연구되고 있으며 광학적 기술에 기초한 소자기술 등이 발전되고 있다. 따라서 본 논문에서는 향후 밀리미터파 대역에서 사용되어질 LMDS(Local Multi-point Distribution Service) 등의 시스템에서 수십기가 헤르츠급의 광원으로 응용 가능한 헤테로다인 방식을 이용한 밀리미터파 대역의 신호생성에 대한 이론적 방법 및 실험적 고찰을 통하여 검증하였다.
