1.55μm 파장 영역의 광섬유에서 광대역 및 평면 초연속체 생성(SC)을 목표로 SC 스펙트럼이 섬유의 군속도 분산(GVD)에 의해 어떻게 영향을 받는지 실험적으로나 이론적으로 연구합니다. 비정상적인 GVD 영역에서는 고차 솔리톤 효과에 의해 광섬유를 통해 전파되는 동안 펌프 펄스의 피크 전력이 높게 유지되므로 라만 효과는 평탄하고 광대역 SC 생성에 악영향을 미칩니다. 제로 GVD 영역에서 TOD(280차 분산)와 자체 위상 변조의 상호 작용은 SC 스펙트럼을 두 가지 주요 구성 요소로 나눕니다. 반면, 정상 GVD 영역에서는 SC 스펙트럼이 비정상 및 제로 GVD 영역의 스펙트럼보다 더 넓고 매끄러워지지만 광섬유의 TOD를 무시할 수 없을 때 여전히 비대칭입니다. 이러한 결과로부터 우리는 일반적인 GVD를 갖는 분산 평탄화된 광섬유가 평탄하고 광대역 SC 생성에 가장 적합하다는 것을 발견했습니다. 실제로 이러한 광섬유에서는 스펙트럼 밀도 변동이 10dB 미만인 XNUMXnm 폭의 SC 스펙트럼이 생성됩니다.

Abstract: Aiming at wideband and flat supercontinuum generation (SC) from optical fibers in the 1.55-µm wavelength region, we study both experimentally and theoretically how SC spectra are influenced by group-velocity dispersion (GVD) of fibers. In the anomalous GVD region, since the peak power of pump pulses is kept high during propagation through the fiber by the higher-order soliton effect, the Raman effect has an adverse effect to flat and wideband SC generation. In the zero GVD region, the interplay of the third-order dispersion (TOD) and the self-phase modulation splits the SC spectrum into two main components. On the other hand, in the normal GVD region, nevertheless the SC spectrum broadens wider and smoother than those in anomalous and zero GVD regions, it is still asymmetric when TOD of the fiber can not be ignored. From these results, we find that a dispersion-flattened fiber with normal GVD is the most suitable for flat and wideband SC generation. A 280-nm wide SC spectrum with the spectral-density fluctuation less than 10 dB is actually generated from such a fiber.
