Low Loss, Highly Nonlinear Waveguides for Transparent Optical Quantum Networks
Fully integrated, low loss, highly non-linear waveguides in thin film lithium niobate represent an enabling technology for emerging quantum networks being developed by the DOE. Today, fully packaged periodically poled lithium niobate (PPLN) ridge waveguides are used to generate high flux, broad band photon pairs which are a key resource in a transparent optical quantum network. While ridge-based photon pair sources are available commercially, highly nonlinear ridge waveguides with more complex functionality to support classical and quantum-based wavelength multicasting and multiplexing need to be developed to ensure the full utility of transparent optical networks can be realized, and enable classical and quantum coexistence. In this DOE SBIR Phase I, AdvR established the feasibility of developing periodically poled magnesium oxide doped lithium niobate (ppMgO:LN) ridge waveguides with advanced poling structures to support quantum and classical multicasting and multiplexing in transparent optical networking and quantum information processing applications under development at the DOE. The key innovation was applying AdvR’s chip level poling technology, which can produce high fidelity poling at the micron level, to produce phase modulated grating patterns in thin film MgO:LN ridge waveguides. This work was performed in collaboration with Dr. Joseph Lukens in the Quantum Information Sciences Group at Oak Ridge National Laboratory, with Dr. Lukens providing insight into the applications and end use of the proposed devices, and AdvR providing expertise in waveguide fabrication and characterization. MgO:LN ridge waveguides offer low loss from UV to IR wavelengths, high power handling capabilities, and high electro-optic and nonlinear performance, making them ideal for use in demanding quantum networking applications that require all optical signal processing.
