title = "Femtoseconds-picoseconds nonlinear optics with nearly-mm thick cholesteric liquid crystals",
abstract = "We have succeeded in fabricating unusually thick (up to ∼ 550 microns), well aligned cholesteric liquid crystals that possess low scattering loss, large operating temperature range and well-defined photonic bandgap in the visible - near infrared regime. These CLC's possess sufficiently large ultrafast (sub-picosecond) electronic optical nonlinearity needed for direct compression, stretching and recompression of femtoseconds-picoseconds laser pulses without additional optics, as demonstrated by theory and experiments. Despite such world-record setting thickness, these CLC's are extremely compact in comparison to other state-of-the-art materials/devices used for similar operations. They are therefore highly promising for miniaturization and reduced complexity of photonic platform/systems for ultrafast pulse modulations.",
