Project description
Unleashing nonlinear integrated photonics with gallium phosphide innovation
Low-intensity light passes through materials without changing their properties and without interaction of waves. High-intensity light such as laser light can modify the properties of materials such that light waves interact, exchanging momentum and energy, and nonlinearities emerge. Nonlinear optics systems are primarily bulky table-top devices. Harnessing nonlinear materials in a photonics integrated chip requires a tremendous reduction in volume. The ERC-funded Pandora project will address this using orientation pattern engineering to augment the intrinsic nonlinearities of the highly nonlinear material, gallium phosphide (GaP), while shaping the resulting crystal to achieve a highly compact form. This could pave the way to nonlinear integrated photonics devices using the single material GaP.
Objective
Nonlinear optics is a thriving research field with numerous practical applications in advanced laser sources, all-optical frequency conversion, optical computing, generation of entangled pairs and quantum cryptography, supercontinuum and terahertz-radiation generation. Traditionally reserved to bulk, tabletop optical systems increasing drive in the photonics community to scale these applications to fit on a chip. The main bottleneck in the convergence of nonlinear optics and integrated photonics is that the volume of nonlinear crystals needs to be reduced by at least a factor 7.
Achieving such a volume reduction requires a major scientific breakthrough. The PANDORA project tackles this issue with the following combination: (a) a material with a high nonlinear figure of merit -- gallium phosphide (GaP); (b) apply orientation patterning to engineer and exalt the intrinsic nonlinear properties of GaP; (c) shape the resulting crystal -- OP-GaP -- into guiding structures that allow ultimate compactness.
The cornerstone of the project is a recent result obtained by the PI and his team, showing that OP-GaP waveguides have the potential to outperform all existing nonlinear crystals with a form factor compatible with photonic integration. The PANDORA project proposes to build upon this result and draw out the full potential of OP-GaP as a single material platform for integrated nonlinear optics.
