Abstract

본 논문에서는 code V 시뮬레이터를 이용하여 광 HDMI 인터페이스에 적용하기 위한 집적형 2채널 TO 구조 광송신기의 광학계 설계를 하였다. 제안된 집적형 2채널 TO 구조 광송신기는 지름의 6.4 mm인 하나의 8 pin TO-CAN 패키지 안에 2개의 VCSEL을 평행하게 부착하고 그 위에 반구(hemisphere) 렌즈가 부착된 직육면체 모양(1 mm(H) × 2 mm(W) × 4 mm(D))의 렌즈필터 블록 (lens filter block) 을 올려놓은 구조이다. 집적형 2채널 TO 구조 광송신기 제작 시 1060 nm/1270 nm와 1330 nm/1550 nm로 두 개 파장씩 묶어 TO-CAN 형태로 제작하므로, 이들 파장 조합에서 반구 렌즈의 지름은 0.6 mm, 볼 렌즈와 렌즈 필터 간격(L)은 파장 1060 nm/1270 nm 조합의 경우 1.7 mm, 파장 1330 nm/1550 nm 조합의 경우 2.0 mm일 때 최적의 결과를 얻을 수 있었다. 이때 렌즈필터 블록의 초점거리(f0)는 1060 nm, 1270 nm, 1330 nm, 1550 nm 파장에 대하여 0.351 mm, 0.354 mm, 0.355 mm, 0.359 mm이었으며 렌즈 필터 블록과 볼 렌즈를 통과한 빛의 초점 위치(F)는 파장 1060 nm/1270 nm 조합의 경우 0.62 mm, 파장 1330 nm/1550 nm 조합의 경우 0.60 mm ~ 0.66 mm이었다.

CODE V

In this paper we design the optical system for an integrated two-channel TO-type optical transmitter to apply the HDMI interface using the code V simulator. The proposed integrated two-channel optical transmitter has two VCSELs attached in parallel on an 8-pin TO-CAN package, on top of which is a lens filter block (1 mm × 2 mm × 4mm) composed of hemispherical lenses and WDM filters. Considering two-channel transmitters manufactured with wavelength combinations of 1060nm/1270nm and 1330nm/1550nm, we obtain the optimum value of the diameter of the hemispherical lens as 0.6 mm for both combinations, and the distances L between the lens filter block and ball lens as 1.7 mm and 2.0 mm for the 1060nm/1270nm and 1330nm/1550nm wavelength combinations, respectively. At this time, the focal length f0 of the lens filter blocks for wavelengths of 1060, 1270, 1330, and 1550 nm are 0.351, 0.354, 0.355, and 0.359 mm, respectively, and the focal lengths F of light passing through the lens filter block and ball lens are 0.62 mm for 1060nm/1270nm and 0.60-0.66 mm for 1330nm/1550nm wavelength combinations.
