A new optical frequency conversion architecture has been proposed that could significantly improve the efficiency and manufacturability of quantum technologies. The novel waveguide design, developed by NIST, uses phase-matched bends to increase nonlinear interaction length and achieve higher conversion efficiency compared to existing methods.
Key features of the architecture include:
– Higher conversion efficiency
– Lower power requirements
– Greater manufacturability due to reduced chip dimensions and higher yield
The technology applies to any suitable nonlinear waveguide material and wavelength, making it versatile for various quantum applications. Implementation could enable rapid wavelength agility for optical communication systems on a low power budget, potentially enabling compact integration into autonomous vehicles.
The proposed architecture consists of several straight sections of phase-matched nonlinear optical waveguides linked by dispersion-engineered bends to allow continuous build-up of the generated light. This innovative approach could revolutionize quantum technologies by making them more efficient, powerful, and manufacturable.
