We demonstrate on-chip all-optical pulse erasure based on four-wave mixing and cross-phase modulation in a dispersion engineered chalcogenide (As2S3) rib waveguide. We achieve an erasure efficiency of similar to 15 dB...

Nonlinear modification of circularly polarized light propagating in holographic-cut cubic crystals is theoretically predicted and experimentally observed. To the best of our knowledge this is the first demonstration o...

Direct diode-laser pumping of a mode-locked Ti:Al2O3 laser is reported. A single 1 W GaN-based diode laser operating at 452 nm is used as the pump laser. Pulse durations as short as 114 fs and average output powers of...

We present a Wannier-function-based time-domain method for photonic-crystal integrated optical circuits. In contrast to other approaches, this method allows one to trade CPU time against memory consumption and therefo...

This work reports the intense emission at 2.7 mu m in a Er3+/Pr3+-codoped fluorophosphate (FP) host glass. This FP glass shows good thermal stability and high transmittance around 3 mu m. The emission characteristic a...

We present a method for single-image passive ranging and three-dimensional (3D) imaging in incoherent light based on chiral phase coding. A chiral linear phase variation across the aperture of an optical system result...
