Lenses

Lenses are pivotal components in many optical systems. In this section, we delve into microlens and metalens designs, showcasing advanced concepts that extend beyond traditional bulk lens-making techniques. Tidy3D’s speed and scalability shine when simulating large microlenses or metalenses in full 3D without any approximations, which is traditionally thought to be impossible.

• 3D optical Luneburg lens
• Metalens in the visible frequency range
• Mid-IR metalens based on silicon nanopillars
• Spherical Fresnel lens
