160-Gb/s Tunable All-Optical Phase-Transparent Wavelength Conversion through Cascaded SFG-DFG in a Linear-Chirped PPLN Waveguide
Optical communications Nonlinear optics integrated optics
2015/6/10
We experimentally demonstrate a 160-Gb/s tunable and phase-transparent wavelength conversion using cSFG-DFG in a linear-chirped PPLN. Thanks to the enhanced conversion bandwidth, no any optical equali...
Stopping Light in a Waveguide with an All-Optical Analog of Electromagnetically Induced Transparency
Light All-Optical Analog Electromagnetically Induced Transparency
2015/8/11
We introduce a new all-optical mechanism that can compress the bandwidth of light pulses to absolute zero, and bring them to a complete stop. The mechanism can be realized in a system consisting of a ...
All-optical transistor action with bistable switching in a photonic crystal cross-waveguide geometry
All-optical transistor action bistable switching photonic crystal cross-waveguide geometry

We demonstrate all-optical switching action in a nonlinear photonic crystal cross-waveguide geometry with instantaneous Kerr nonlinearity, in which the transmission of a signal can be reversibly switc...
