- W202320458 abstract "리튬나이오베이트 기판의 분극 반전 기술을 이용하여 300Hz 대역 광변조기를 제작하였고 60 GHz 광캐리어 발생기로 응용하였다. 주기적인 분극반전은 도파광과 RF사이의 QVM(Quasi-Velocity-Matching)을 유발하여 대역변조를 가능하게 하였다. 제작된 광변조기는 30.3 GHz에서 최대 변조효율을 보였으며, 3 dB 변조 대역폭은 약 5.1 GHz로 측정되었다. DSB-SC(Double Sideband Suppressed Carrier) 측정 실험을 통해 입사된 광 주파수로부터 30 GHz 간격으로 USB(Upper Sideband)와 LSB(Lower Sideband)를 발생시켰으며 입사광의 스펙트럼은 발생된 USB 혹은 LSB에 비해 28 dB정도 억제됨으로써, 30GHz 대역 광변조기가 60 GHz 광캐리어 발생기로 응용될 수 있음을 보였다. A novel 60GHz optical carrier generator with a polarization domain-inverted structure is suggested and is demonstrated. The two arms of the Mach-Zehnder optical waveguide are periodically poled for quasi-phase velocity matching between the optical wave at 1550nm and the RF wave at 30 GHz. The center frequency of band-pass modulation and the 3 dB bandwidth of the fabricated modulator were measured to be 30.3 GHz and 5.1 GHz, respectively. Sub-carriers with the frequency difference of 60GHz waeregenerated under appropriate DC biac voltage application while the carrier was suppressed to lead to the power ratio between the modulated sub-carrier and the suppressed fundamental carrier of 28 dB, which proves that double sideband- suppressed carrier(DSB-SC) operation can be realized by the suggested single device." @default.
