Direct femtosecond pulse compression with miniature-sized Bragg cholesteric liquid crystal
Liyan Song, Shenhe Fu, Yikun Liu +3
Direct compression of femtosecond optical pulses from a Ti:sapphire laser oscillator was realized with a cholesteric liquid crystal acting as a nonlinear 1D periodic Bragg grating.…

Buffering and Trapping Ultrashort Optical Pulses in Concatenated Bragg Gratings
Shenhe Fu, Yikun Liu, Yongyao Li +4
Strong retardation of ultrashort optical pulses, including their deceleration and stoppage in the form of Bragg solitons in a cascaded Bragg-grating (BG) structure, is proposed. Th…
