Fabrication and Characterization of Lateral p-i-n photodiodes and design of stub mounted optically controlled phase shifter
수평형 p-i-n 광다이오드의 제작, 특성 측정 및 광제어 스터브 장착 위상기의 설계
Abstract
Lateral p-i-n photodiodes have been fabricated, electrically tested, and incorporated into microwave control circuits such as an optically excited microwave atttenuator and reflection type phase shifter. Circuit design procedures for the loaded-line phase shifter with the optically controlled p-i-n photodiode are presented. The equal loss loading mode presented for the first time for the phase shifter circuits with lossy load allows an equal insertion loss of the phase shifter in both of its phase states. It is found that the insertion loss of the equal loss loading mode phase shifter constructed with the fabricated p-i-n photodiode load are about 3dB for 11.25
