[摘要]：We design As(2)Se(3) and As(2)S(3) chalcogenide photonic nanowires to optimize the soliton self-compression with short distances and ultralow input pulse energy. We numerically demonstrate the generation of single optical cycle in an As(2)S(3) photonic nanowire: a 5.07 fs compressed pulse is obtained starting from 250 fs input pulse with 50 pJ in 0.84 mm-long As(2)S(3) nanowire. Taking into account the high two photon absorption (TPA) coefficient in the As(2)Se(3) glass, accurate modeling shows the compression of 250 fs down to 25.4 fs in 2.1 mm-long nanowire and with 10 pJ input pulse energy.
