Abstract

We fabricated PIN-Photodiodes with a single mode fiber for analog communications and analyzed characteristics of the devices. The fabricated PIN-Photodiode shows a bandwidth of 1.5 GHz, a dark current of 20 p4 a capacitance of 0.48 pF, and the responsivity of 0.9 V/W, a second order distortion of -72 dBc. In this paper, we developed a new optical Packaging technology that is aligning in real-time monitoring of both responsivity and IM2 characteristics. As a result responsivity has been improved by 0.03 V/W, and also U has been improved by $3\~5\;dBc$. On the other hand, failure ratio has been reduced by $3.5\%$.

본 논문에서는 단일모드 광섬유를 부착한 analog용 PIN-Photodiode를 제작하고 소자의 특성을 분석하였다. 제작된 analog 용 PIN-photodiode의 대역폭은 1.5 GHz이였으며, 암전류는 20 pA이고, 정전용량은 0.48 pF이였으며, 응답도(responsivity)는 0.9 V/W 이고, 2차 상호변조(IM2, second order distortion)는 -72 dBc이였다. 본 논문에서는 응답도와 IM2 특성을 실시간으로 모니터링하며 정렬하는 새로운 광 패키징 기술을 개발하였다. 그 결과 응답도는 0.03 V/W 향상되었으며, IM2는 $3\~5dBc$ 향상 되었고, 부적합 발생률도 $3.5\%$ 감소하였다.
