WebJan 1, 1997 · The mirror is perhaps the oldest optical element. Looking glasses were discovered in Egyptian pyramids built in 1900 BC. Plane, or flat, mirrors are found in practically every home today. Spherical, or parabolic, mirrors are often used in optical systems instead of lenses. When a ray of light is incident upon a surface, components of … WebApr 19, 2024 · The integration of optical — or “photonic” — and electronic components on the same chip reduces power consumption still further. Optical communications devices are on the market today, but they consume too much power and generate too much heat to be integrated into an electronic chip such as a microprocessor.
