Optoelectronics refers

Optoelectronics refers to technologies and devices that combine optical and electronic properties and processes. These technologies are focused on the manipulation and detection of light signals using electronic components and related electronics.

Optoelectronic devices and systems use the principles of photonics and electronics to transmit, manipulate and detect light. Here are some examples of optoelectronic devices:

LED (Light Emitting Diode): An LED is an optoelectronic device that emits light when a current passes through it. LEDs are used in a variety of applications including lighting, indication and image displays.

Laser diode: A laser diode is an optoelectronic device that generates coherent light in the form of a laser beam. Laser diodes are used in communication systems, medicine, industry and many other areas.

Photodiode: A photodiode is an electronic device that generates an electric current when light is absorbed. It is used to detect light signals and is crucial in a variety of applications such as photography, optical communication, and sensing.

Phototransistor: A phototransistor is a device that combines the properties of a transistor and a photodiode. When illuminated, it generates an electric current that can be used to amplify and detect light signals.

Optical sensors: Optoelectronic sensors use light to detect various physical quantities such as position, movement, pressure and many others. These sensors are used in a wide range of applications.

So, when something is labeled "optoelectronic," it means that it is a combination of electronics and optics, where electronic devices interact with light to achieve specific functions or applications.
