quantum well
Quick Summary
A quantum well is a structure made of thin layers of different semiconductor materials. These layers are typically only about 10 nanometers thick, with many layers stacked together to form a device about 1 micrometer thick.
When a voltage is applied, the transmission of photons through these layers changes significantly, acting as an optical modulator. This property is crucial for photonic switching devices and is a key concept in modern telecommunications and optoelectronics, enabling efficient processing and transmission of data at high speeds. Quantum wells exploit quantum mechanical properties to confine electrons, influencing their behavior and enabling specific electronic and photonic functions.12
