Optoelectronics
Optoelectronics :
Optoelectronics is a branch of electronics that overlaps with physics. The field concerns the theory, design, manufacture, and operation of hardware that converts electrical signals to visible or infrared radiation(infrared) energy, or vice-versa. Examples of optoelectronic components include photocells, solar cells, optoisolators (also called optical couplers or optocouplers), LEDs (light-emitting diodes), and laser diodes. Applications include electric eyes, photovoltaic power supplies, various monitoring and control circuits, and optical fibercommunications systems
