Abstract

Polymeric multi-mode optical waveguides were fabricated for parallel optical interconnection. Waveguide structures were molded by a Ni mold master using a hot embossing technique. The Ni mold master was manufactured by LIGA process. Multimode optical waveguides with a 48$\times$47 ${\mu}{\textrm}{m}$$^2$cross-section were produced by a simple two-step process. The propagation losses of the multimode waveguide measured at 0.85 ${\mu}{\textrm}{m}$ and 1.3 ${\mu}{\textrm}{m}$ wavelengths were 0.38 dB/cm and 0.66 dB/cm, respectively.

병렬 광접속용 다중모드 고분자 광도파로를 제작하였으며, 도파로 구조는 LIGA 공정에 의해 제작된 니켈 성형 마스터에 의해 hot embossing기술을 이용하여 성형하였다. 도파로 크기가 48$\times$47$\mu\textrm{m}$$^{2}$인 다중모드 광도파로를 단순 2단계 공정에 의해 제작하였으며, 0.85$\mu\textrm{m}$과 1.3$\mu\textrm{m}$ 파장대역에서 측정한 다중모드 광도파로의 도파손실은 각각 0.38dB/cm와 0.66dB/cm이었다.
