What is Optoelectronics?

A new Laboratory of Advance Synthesis and Characterisation (LASC) in Gujarat is developing LASC probe stations for universities in India and abroad for the investigation of opto-electronic properties in a wide range of materials.

About Optoelectronics:

  • Optoelectronics is the study and application of light-emitting or light-detecting devices.
  • It is widely considered a sub-discipline of photonicsPhotonics refers to the study and application of the physical science of light.
  • Optoelectronics is a fast-emerging technology field that consists of applying electronic devices to sourcing, detection, and control of light. 
  • It is largely based on semiconductor materials. These exhibit suitable bandgap energiefor absorbing near-infrared and visible light, and their electric conductivity (albeit not perfect) is also essential for such applications.
  • Examples of optoelectronic devices consist of:
    • Telecommunication laser
    • Optical fibre
    • Blue laser
    • LED traffic lights
    • Photodiodes
    • Solar cells
  • These devices are used in a wide variety of application areas, such as military services, automatic access control systemstelecommunications, medical equipment, and more.
  • Optoelectronics should not be confused with electro-optics, as this field is a wider branch of physics that deals with the interaction of electric fields and light, without concern if an electronic device is involved or not.
