Extracting photons efficiently from quantum sources, such as atoms, molecules, and quantum dots, is crucial for various nanophotonic systems used in quantum communication, sensing, and computation. To improve the performance of these systems, it is not only necessary to provide an environment that maximizes the number of optical modes, but it is also desirable to guide the extracted light toward specific directions. One way to achieve this goal is to use a large area metasurface that can steer the beam.

- Adjoint optimization is a powerful technique for designing nanophotonic devices, helping to shape their properties effectively.
- The proposed method employs level-set techniques with b-spline surfaces to manage the minimum feature sizes during the design process.
- This approach has been successfully applied to create a wavelength demultiplexer and a nanophotonic device for artificial neural computing, demonstrating easy control over feature sizes.
