초록

광결정 광섬유에서 생성되는 초 연속스펙트럼의 특성을 일반화된 비선형 슈뢰딩거 방정식과 split step 퓨리에 방법을 이용하여 전산모사 하였다. 그 결과를 바탕으로 200 fs 펄스폭을 갖는 Ti:sapphire 레이저와 광결정 광섬유를 이용하여 650 nm부터 900 nm에 이르는 파장영역에서 ±4 dB 이하의 평탄도를 가지는 초 연속스펙트럼을 실험적으로 생성하였다.

Abstract

The characteristics of the supercontinuum generated in photonic crystal fibers were investigated by using the generalized nonlinear Schrödinger equation and the split-step Fourier method. Based on the simulated results, we generated the supercontinuum spectrum with the flatness of ±4 dB in the wavelength range of 650 to 900 nm by employing a 200-fs pulse of Ti:sapphire laser and a commercial photonic crystal fiber.
