Abstract

The integrated external cavity laser has been fabricated with a 1550 nm FP-LD, an optical filter, a micro ball lens and accurate ceramic blocks using a micro-block stacking (MBS) technique. The integrated external cavity laser module whose size is only $2.0{\times}2.1{\times}0.7\;mm^3$ has been mounted on the TO-CAN package. For the case of the 1.8% transmission filter, the single mode characteristic has been obtained with the optical power of -27.1 dBm and the SMSR of 31.7 dB.

Micro-Block Stacking(MBS) 방법으로 1550nm FP-LD와 박막 필터, 마이크로 볼 렌즈를 사용하여 집적형 외부 공진기 레이저를 제작하였다. 제작한 집적형 외부 공진기 레이저 모듈 크기는 $2.0{\times}2.1{\times}0.7\;mm^3$이었으며 TO-CAN 형태로 패키징하였다. 투과율이 1.8%인 박막 필터를 사용한 집적형 외부 공진기 레이저의 경우 광출력이 -27.1 dBm이고 SMSR이 31.7 dB인 양호한 단일모드 레이저 특성을 얻을 수 있었다.
