We have investigated the power threshold of discrete Kerr surface solitons at the interface between discrete and continuous 1D AlGaAs medium. Distinct thresholds were measured for interface solitons localized at different sites from the interface.
Cross-Phase modulation (XPM) is investigated in AlGaAs nanowires by way of cross- polarised co-propagating pulses. A XPM to SPM (Self-Phase Modulation) ratio of 0.92 is determined at 1557 nm.
Side-coupled-integrated-spaced-sequence-of-resonators (SCISSORs) with many rings are important for controlling the behavior of light propagation. We show the linear performance of SCISSORs in high index-contrast AlGaAs in 1, 2, 4, and 8 ring configurations.
