Nano and Micro Optics

The study and manipulation of light at extremely small sizes, usually at the nanometer (nm) and micrometre (μm) levels, is the focus of nano and micro optics. Through nanostructures like plasmonic nanoparticles and metasurfaces, light can be controlled in innovative ways thanks to the field of nano optics, which studies materials and structures that function at the nanoscale. nano lenses and integrated photonic circuits are examples of optical systems and components at the micrometre size that are the subject of nano optics. Miniaturised optical devices, high-resolution imaging, and breakthroughs in sectors such as sensing, medical diagnostics, and telecommunications depend on these two fields. The advancement of technology is greatly aided by nano and micro optics, which make compact and highly effective optical systems possible.
