Tunable wavelength converter using cascade of sum frequency mixing and difference frequency mixing in quasi-phase matched lithium niobate

Yutaka Fukuchi

We investigate bandwidth limitation of tunable wavelength conversion from an arbitrary wavelength to another arbitrary one using the cascaded second-order nonlinear effect in quasi-phase matched lithium niobate waveguides. Critical pulse width to be wavelength-converted is proportional to the device length, and its ratio is 1.6ps/cm.

Improved cascaded sum and difference frequency generation-based wavelength converters in low-loss quasi-phase-matched lithium niobate waveguides

Amirhossein Tehranchi, Raman Kashyap

We numerically evaluate the wavelength converters based on cascaded sum and difference frequency generation in quasi-phase-matched lithium niobate waveguides with and without loss. A technique is also proposed to flatten the response by increased detuning of the pump wavelength. We present the criteria for the design of waveguide length and the assignment of pump power to achieve the desired efficiency, ripple and bandwidth, assuming a large pump wavelength difference of 75 nm.

Single-to-Multiple Channel Wavelength Conversions and Tuning of Picosecond Pulses in Quasi-Phase-Matched Waveguides

Jian Wang, Junqiang Sun, Luo Chuan-hong +3 more

We report the single-to-multiple channel wavelength conversions of 1.57-ps pulses based on cascaded second-harmonic generation and difference frequency generation in quasi-phase-matched periodically poled lithium niobate waveguides. For single-to-single channel wavelength conversion, no external cavity laser is required with use of a fibre ring laser. The conversion efficiency is about -21.44 dB. The converted idler wavelength can be tuned from 1526.4 nm to 1537.5 nm as the lasing pump wavelength is varied from 1566.1 nm to 1555.0 nm. By employing several input pumps, tunable single-to-dual and single-to-triple channel wavelength conversions are experimentally demonstrated.
