Simultaneous observation of inverted and noninverted wavelength conversion of picosecond pulses in LiNbO₃ waveguides

Abstract

We propose and demonstrate simultaneously inverted and noninverted wavelength conversion of picosecond pulses in periodically poled LiNbO3 waveguides. By only use of sum‐frequency generation, inverted wavelength conversion from the signal wavelength to pump wavelength both within the 1.5‐μm band is experimentally verified. By exploiting cascaded sum‐ and difference‐frequency generation (SFG + DFG), both inverted and noninverted wavelength conversion are observed in the experiments. © 2006 Wiley Periodicals, Inc.

Simultaneously All-Optical Inverted and Noninverted Wavelength Conversion Employing Ultra-Small Silicon-on-Insulator Waveguide

“…Many previous reports focus on single-to-single channel conversion, operating with inverted or non-inverted modulation, but some recent researches present results of single-to-dual and simultaneous inverted and non-inverted conversion [14][15][16]. However, the designed devices are not so easily used in high integration schemes.…”
