광결정 섬유(photonic crystal fiber: PCF)를 포함하는 광대역 광원의 출력 모드를 제어하기 위한 모드 제어 시스템 및 방법이 개시된다. 모드 제어 시스템은: 측정 데이터를 생성하기 위해 상기 광대역 광원으로부터 방출되는 방사선의 하나 이상의 파라미터를 측정하도록 구성된 적어도 하나의 검출 유닛; 및 상기 측정 데이터로부터, 상기 광대역 광원으로부터 방출되는 상기 방사선의 모드 순도를 평가하도록 구성된 처리 유닛을 포함한다. 상기 평가에 기초하여, 상기 모드 제어 시스템은 상기 광대역 광원의 하나 이상의 펌프 결합 상태의 최적화를 위한 제어 신호를 발생시키도록 구성된다. 상기 펌프 결합 상태들은 상기 광결정 섬유의 섬유 코어에 대한 펌프 레이저 빔의 결합과 관련된다. Disclosed is a polarization control system and method. The system controls the output polarization of a broadband light source comprising a waveguide. The system comprises at least one detection unit configured to measure one or more parameters of radiation emitted from said broadband light source to generate measurement data; and comprises a processing unit configured to infer a polarization property of said radiation emitted from said broadband light source from said measurement data. Based on the evaluation, the polarization control system generates a control signal for optimization of the pump polarization conditions of said broadband light source. The pump polarization conditions relating to the coupling of a pump laser beam with respect to a fiber axis of the photonic crystal fiber.
