Opto-Electronics

• 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 Opto electronics:

• Optoelectronics is the study and application of light-emitting or light-detecting devices. 
• It is widely considered a sub-discipline of photonics. Photonics 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 energies for 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
