摘要： A method of producing photonic crystal fiber (PCF) preforms, comprising obtaining a plurality of preform capillaries; measuring the wall thickness of each of the plurality of preform capillaries along at least a portion of its circumference at one or more axial positions; selecting a number of preform capillaries from the plurality of preform capillaries at least based on a thickness criterion,; and placing the selected preform capillaries in a glass tube (or jacket tube) to form a PCF preform having at least one ring arrangement of the selected preform capillaries; wherein the selected preform capillaries are oriented such that the portion of each of the selected preform capillaries, within which the measured wall thicknesses vary from the nominal wall thickness by no more than the maximum thickness variation, faces a longitudinal axis of the glass tube, said glass tube being substantially symmetrical about the longitudinal axis.

摘要： 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.

摘要： Disclosed is a mode control system and method for controlling an output mode of a broadband light source comprising a photonic crystal fiber (PCF). The mode control 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 a processing unit configured to evaluate mode purity of said radiation emitted from said broadband light source, from said measurement data. Based on the evaluation, the mode control system is configured to generate a control signal for optimization of one or more pump coupling conditions of said broadband light source. The pump coupling conditions relate to the coupling of a pump laser beam with respect to a fiber core of the photonic crystal fiber.

摘要： A source control arrangement for a radiation source comprising a hollow-core photonic crystal fiber (HC-PCF) having a hollow core with a core diameter, comprising: at least one processor; and a pulse chirping arrangement configured to receive pulsed pump radiation and controllably chirp the pulsed pump radiation so as to output chirped pulsed pump radiation for exciting a working medium comprised within the hollow core of the fiber at a pressure. The at least one processor is operable to configure source parameters of the radiation source, which include one or both of the pressure and a pulse chirp parameter, such that the chirped pulsed pump radiation undergoes a spectral broadening process within the HC-PCF, thereby generating an output radiation having a predefined spectrum for a reference core diameter of the HC-PCF, so as to compensate for variation in the core diameter with respect to the reference core diameter.
