Abstract

Photonic crystal fibers(PCFs) with silica cores within an away of air holes have unique properties. Broad band single-mode and the octave-spanning supercontinuum generation, impossible to achieve in classical fibers, can be realized. The design of PCFs is very flexible. There are two parameters to manipulate: air hole diameter, and lattice pitch. We introduced a fabrication process for control of the parameters to obtain endlessly single mode PCF, which is single mode in a large wavelength range, and highly nonlinear PCF. The numerical analysis and experiments are included.

실리카 코어 주변에 주기적인 공기층을 가지는 광자결정 광섬유는 넓은 파장 영역을 통한 단일모드의 구현 또는 1옥타브 이상의 광대역 연속광 발생과 같은 기존의 광섬유로는 불가능한 독특한 특성을 갖도록 유연하게 설계할 수 있다. 광자결정 광섬유의 설계에 사용되는 변수로는 공기층의 직경과 간격이 있으며 이러한 변수의 조절을 위한 공정을 도입하여 넓은 파장영역을 통한 단일모드 구현과 높은 비선형 특성을 가지는 광자결정 광섬유를 각각 제작 하였고 수치적 계산과 실험을 통해 그 특성을 살펴보았다.
