초록

Modified Airy 함수를 이용하여 언덕형 굴절률 분포를 갖는HOF를 해석하였으며, 정교한 결과를 갖는 고유 방정식을 도출하였다. 언덕형 HOF의 경우 기존의 계단형 HOF에 비하여 중공 영역 내 감쇠 전계의 기울기를 임의로 가파르게 조절할 수 있음을 보였다.

Abstract

Arbitrary graded-index HOF(Hollow Optical Fibers) are analyzed using the modified Airy function, and the corresponding eigenvalue equation that renders precise results is derived. For graded index HOF, the gradient of an evanescent field in hollow region could be adjusted more sharply than the conventional step-index HOF and the feasibility of more effective atom-guiding is confirmed.
