Integrated optics Wavelength conversion devices Integrated optics Nonlinear
2015/5/22
We demonstrate parametric conversion with simultaneous 19.5dB amplification, of a mid-IR 2440nm signal to the telecom-band near 1620nm, using silicon nanophotonic wires.Conversion over 820nm is facili...

2015/6/10
We build and characterize a fiber-based source of 1310-nm polarization entanglement with the highest reported fidelity to a maximally entangled state, 99.6% ± 0.15% as characterized via coincidence ba...
Ultra Low Nonlinear Telecom Fibre by Hole Assisted Technique
Nonlinear Telecom Fibre Hole Assisted Technique
2015/7/16
Hole assisted fibre with less than half nonlinearity of standard SMFs was investigated. Fabricated fibre has Aeff of 180μm 2 , reduced n2 and larger dispersion coefficient, simultaneously. Low loss sp...
Optical Pulse Shaping for Ultrahigh-Bit-Rate Telecom Applications based on III-V Integrated Waveguide Bragg Grating
Optical Pulse Shaping Ultrahigh-Bit-Rate Telecom Applications III-V Integrated Waveguide Bragg Grating
2015/8/4
We introduce a general linear pulse-shaping approach based on III-V integrated single-waveguide Bragg gratings for synthesizing arbitrary complex waveforms with (sub-)picosecond resolutions. Pulse cod...
