【Growth Market!】Basic Knowledge of Optical Semiconductors

【Growth Market!】Basic Knowledge of Optical Semiconductors

【Growth Market!】Basic Knowledge of Optical Semiconductors

This time, we present a catalog on optical semiconductors. Semiconductors refer to materials whose electrical conductivity is intermediate between that of metals and insulators. Among them, optical semiconductors are a general term for light-emitting devices that convert electrical signals into optical signals, light-receiving devices that convert optical signals into electrical signals, and composite devices that combine both light-emitting and light-receiving elements. In this issue, we will introduce the basic knowledge of optical semiconductors. Please take a look, and if you have any questions, feel free to consult with us at Equal. 【Keywords】 III-V semiconductors, silicon, organic semiconductors, LED, laser diodes, photodiodes, optical amplifiers, optical modulators.
