Abstract

We proposed a fusion splicing method for low splicing loss between a single-mode fiber(SMF) and two different photonic crystal fibers(PCFs) such as a photonic bandgap fiber(PBGF) and highly nonlinear photonic crystal fiber(NL-PCF). The splicing loss between the SMF and PBGF is affected by air-hole collapse. Therefore, we optimized fusion splicer and reduced a splicing loss below 1.22 dB. We also inserted a Intra High Numerical Aperture(UHNA) fiber between the SMF and NL-PCF to achieve a splicing loss of below 2.59 dB.

단일모드 광섬유(SMF)와 포토닉 밴드갭 광섬유(PBGF), SMF와 고비선형 광자결정 광섬유(NL-PCF)의 저손실 융착접속을 위한 방법을 제안하였다. SMF와 PBGF를 융착접속할 경우 PBGF의 공기구멍 붕괴현상에 의한 손실이 가장 큰 영향을 미치므로 PBGF의 공기구멍을 유지시키기 위해서 광섬유 융착접속기를 최적화하여 접속손실을 1.22 dB이하로 줄였다. SMF와 NL-PCF의 융착접속시에는 Ultra High Numerical Aperture(UHNA)광섬유를 두 광섬유 사이에 삽입하여 융착접속하는 방법을 적용하여 평균 2.59 dB이하로 접속손실을 줄였다.
