Flexible wavelength conversion via cascaded second order nonlinearity using broadband SHG in MgO-doped PPLN

Junfeng Zhang, Yuping Chen, Feng Lu +1 more

In this paper, we experimentally demonstrate flexible wavelength conversion, in which the input signals can be freely converted to output wavelengths through widely and arbitrarily tuning the pump wavelength within a broad second harmonic (SH) bandwidth up to 25 nm. The scheme is based on the cascaded chi (2) process in a 20-mm periodically poled MgO-doped LiNbO(3) (PPMgLN). Also, wavelength broadcasting can be performed by simultaneous use of multiple pumps with wavelengths located in the broad SH bandwidth.

All optical wavelength broadcast based on simultaneous Type I QPM broadband SFG and SHG in MgO:PPLN

Mingjun Gong, Yuping Chen, Feng Lu +1 more

We experimentally demonstrate wavelength broadcast based on simultaneous Type I quasi-phase-matched (QPM) broadband sum-frequency generation (SFG) and second-harmonic generation (SHG) in 5 mol.% MgO-doped periodically poled lithium niobate (MgO:PPLN). One signal has been synchronously converted into seven different wavelengths using two pumps at a 1.5 microm band via quadratic cascaded nonlinear wavelength conversion. By selecting different pump regions, i.e., selecting different cascaded chi((2)):chi((2)) interactions, the flexible wavelength conversions with shifting from one signal to single, double, and triple channels were also demonstrated.

Ultrabroadband flattop wavelength conversion based on cascaded sum frequency generation and difference frequency generation using pump detuning in quasi-phase-matched lithium niobate waveguides

Meenu Ahlawat, Amirhossein Tehranchi, Chang Qing Xu +1 more

Flattop wavelength conversion over a 70 nm bandwidth in a 45-mm-long periodically poled lithium niobate (PPLN) waveguide based on nonlinear cascaded sum frequency generation (SFG) and difference frequency generation processes using two separated wavelengths, is realized. A 2 dB peak-to-peak ripple over the conversion bandwidth in the C band is observed when the two pumps are fixed for perfectly phase-matched SFG conversion; this is significantly reduced to 0.5 dB by slight detuning of one of the pumps to a longer wavelength. We also demonstrate multichannel broadcasting using two pumps to convert one signal wavelength to three idlers. Using the aperiodically poled lithium niobate waveguide increases the idler separation.

Spatial ultrafast switching and frequency conversion in lithium niobate waveguide arrays

Thomas Pertsch, Robert Iwanow, Roland Schiek +5 more

We demonstrate phase-insensitive, ultrafast, all-optical spatial switching and frequency conversion in quadratically nonlinear waveguide arrays in periodically poled lithium niobate. Routing of milliwatt signals with wavelengths in the communication band (1550 nm) is achieved without pulse distortions by parametric interaction with a control beam with 10-W power and wavelengths near 775 nm.

All-Optical Wavelength Conversion Based on the Cascaded Sum and Difference Frequency Generation in a Periodically Poled Lithium-Niobate Waveguide

Jian Wang

The principle of all-optical wavelength conversion based on the cascaded sum and difference frequency generation (SFG+DFG) in quasi-phase-matched (QPM) periodically poled LiNbO3 (PPLN) waveguides is introduced. The conversion efficiency of the wavelength converter is calculated. The influences of the powers and span of two pumps on the conversion efficiency are analyzed. Bandwidth of one pump wavelength is discussed. The tuning is about 0.5 nm. The signal pulse width is compressed about 0.68 times.
