⭐ Inverse Design of the Week ⭐  💎 GaP Photon Extractor for NV Centers in Diamond Enhancing photon collection efficiency from color centers is essential for advancing solid-state qubit systems in quantum information and metrology applications. High refractive index materials like diamond face total internal reflection, limiting photon extraction from embedded qubits. This week, we delve into the inverse design of a Gallium Phosphide (GaP) photon extractor that significantly improves photon collection efficiency. Using Tidy3D's inverse design, we optimized a compact 1.5 μm x 1.5 μm design region atop a diamond substrate, following the novel work from Prof. Kai-Mei Fu group and collaborators (https://lnkd.in/grwBsiEP). The design maximizes the minimum upward flux across three dipole source orientations (‘x’, ‘y’, and ‘z’), achieving:   • >10x enhancement for in-plane dipole orientations.   • >200x enhancement for out-of-plane dipoles compared to the no-extractor baseline. Fabrication constraints were incorporated through a smoothing and projection method, ensuring compliance with electron beam lithography’s 50 nm feature size requirements. The optimization process culminated in a design robust to binarization. Explore the details of our design workflow, from defining dielectric structures and running baseline simulations to achieving optimal flux enhancement and fabrication readiness. 💡 Check out our Python notebook for step-by-step insights here: https://lnkd.in/guFQ9Ntm #Photonics #InverseDesign #QuantumTechnology #Tidy3D #Flexcompute

High-lift aerodynamics remains one of the more complex challenges in CFD, requiring accurate predictions of separated flows and vortex interactions. This study demonstrates how advanced turbulence models and simulation techniques can improve the precision of high-lift predictions, helping refine designs for takeoff and landing scenarios. With insights from Flow360, these improvements contribute to more reliable aerodynamic analysis for modern aircraft.

🌟 Inverse Design of the Week 🌟 Inverse Design of a Quantum Emitter Light Extractor Quantum emitters such as color centers and trapped ions often suffer from poor light extraction efficiency due to their placement in materials where much of the emitted light is trapped by total internal reflection or absorbed before it can exit the material. A light extractor is often engineered to overcome these challenges by enhancing the coupling of the emitted photons to modes that can propagate into free space or waveguides. Designing a high-efficiency extractor is a nontrivial task. In this example, we use inverse design by embedding a point dipole as our quantum emitter in a dielectric region. We then topology-optimize this region to maximize the extraction of the TE mode in an output waveguide connected to this region. In addition, we customize this optimization by using a mask to impose a constant dielectric within a circle around our quantum emitter to protect it from etching. Additional minimal feature size constraints are imposed in the optimization to ensure fabricability. In the end, we can achieve a coupling efficiency above 80%. 👏 Check out our example and experience the new era of photonic optimization: https://lnkd.in/gAW7cRkT #Photonics #Devices #TopologyOptimization #InverseDesign #Tidy3D #Flexcompute

🌟 Inverse Design of the Week 🌟 Inverse Design Optimization of a Plasmonic Nanoantenna Metasurface Plasmonic resonances in nanoantennas enable unique ways of controlling light, with numerous applications across the photonics industry. As we’ve showcased in previous weeks, topology optimization is a powerful tool for quickly designing and optimizing such structures. However, performing topology optimization on dispersive materials like metals can be challenging, and the implementation is often not straightforward. Fortunately, Tidy3D's powerful autograd integration greatly simplifies this process. This week, we leverage Tidy3D’s speed and robustness to perform gradient-based topology optimization targeting field enhancement at a specific location. In just 20 optimization steps (40 FDTD simulations), we achieved a field enhancement of up to 680 times while respecting fabrication constraints. Curious to see how this was achieved?
