Phase-matched waveguide four-wave mixing scaled to higher peak powers with large-core-areahollow photonic-crystal fibers
FREE-DOWNLOADSO Konorov, EE Serebryannikov, AB Fedotov… – Physical Review E, Hollow photonic-crystal fibers with large core diameters are shown to allow waveguide nonlinear-optical interactions to be scaled to higher pulse peak powers. Phase-matched four-wave mixing is predicted theoretically and demonstrated experimentally for millijoule
Dynamic control of higher-order modes in hollow-core photonic crystal fibers
FREE-DOWNLOADTG Euser, G Whyte, M Scharrer, JSY Chen… – Optics … We present a versatile method for selective mode coupling into higher-order modes of photonic crystal fibers, using holograms electronically generated by a spatial light modulator. The method enables non-mechanical and completely repeatable changes in the coupling conditions.
Low-loss polarization-maintaining fusion splicing of single-mode fibers and hollow-core photonic crystal fibers, relevant for monolithic fiber laser pulse compression
FREE-DOWNLOADJT Kristensen, A Houmann, X Liu… – Optics Express We report on highly reproducible low-loss fusion splicing of polarization-maintaining single-mode fibers (PM-SMFs) and hollow-core photonic crystal fibers (HC-PCFs). The PM-SMF-to-HC-PCF splices are characterized by the loss of 0.62 ± 0.24 dB, and polarization extinction ratio of
