Basics of photonics

Photonics is the study of the generation, manipulation, and detection of light. It encompasses a wide range of technologies, from the basic principles of light generation and detection to the design and fabrication of advanced photonic devices.

Photonic devices

Photonic devices are devices that use light as a means of communication, computation, and sensing. They include a wide range of technologies, such as LEDs, photodetectors, and solar cells.

LED

A light-emitting diode (LED) is a semiconductor device that emits light when an electric current is passed through it. LEDs are widely used in various applications such as lighting, displays, and optical communication.

Photodetectors

A photodetector is a device that converts light into an electrical current or voltage. They are widely used in various applications such as optical communication, sensing, and imaging.

Photodiode (Junction type)

A photodiode is a type of photodetector that uses a p-n junction to convert light into an electrical current. They are widely used in various applications such as optical communication, sensing, and imaging.

PIN Photodiode

A PIN photodiode is a type of photodiode that uses a p-type, intrinsic, and n-type semiconductor layers to convert light into an electrical current. They are widely used in various applications such as optical communication, sensing, and imaging.

Solar cell

A solar cell is a device that converts light energy into electrical energy. They are widely used in various applications such as solar power generation and satellite power.
