Abstract

Optical 60 ㎓ millimeter-wave (MMW) signal generation is demonstrated using the sideband injection-locking method in the master/slave configuration, where two slave lasers are locked to two among several side-bands produced by the direct rf-modulation of a master laser. These two locked slave laser outputs beat against each other in the photo-detector and produce stable and very pure 60 ㎓ signals.

Master laser(ML)의 직접 변조로 생성된 여러 개의 side-bands 중 두 개의 target band게 두 개의 Slave laser(SL)가 각각 lock이 되도록 하는 side-band injection-locking 방법을 이용하여 광학적 60㎓의 밀리미터파 신호를 구현하였다 ML에 lock이 된 두 SL의 output들은 photo detection시 서로 beating하여 안정적이고 매우 깨끗한 60㎓ 신호를 생성하였다.
