Plasmonic waveguides leverage surface plasmon polaritons to confine and guide light at subwavelength scales, enabling the miniaturization of photonic circuits. They offer a unique combination of optical and electronic properties, making them crucial for applications in sensing, data processing, and telecommunications.
Photonic structures are engineered materials that manipulate the flow of light, often by creating periodic variations in refractive index to control photonic band gaps. These structures are crucial in developing advanced optical devices, enhancing communication technologies, and improving energy efficiency in applications like solar cells and LEDs.
A phase grating is an optical device that alters the phase of incoming light waves rather than their amplitude, creating interference patterns that can be used to manipulate light propagation. This phenomenon is crucial in applications like beam steering, holography, and optical communication systems, where precise control over light is required.
