What You Need to Know About Optoelectronic Devices


Just like any other industry, electronics and technology have their complexities. To consider this, we will slowly discuss and identify electronic components for a lighter approach. This is the essential groundwork for understanding Optoelectronics. Multiple topics will be covered, but rest assured that these will better understand how specific components work. 


Familiarity with individual components is common for their market and can also be very specific for procurement specialists as they use codes such as the lpddr3 RAM of Micron Technology. Electronic components are different in terms of function, types, application, and alike, which are the determinants of the product categories. Today, we will discuss the category in which diodes and LEDs belong, Optoelectronics.


What is an Optoelectronic?

This is a branch of technology, a sub-discipline of photonics, which is a study of the physical science of light. Optoelectronic devices and components only operate when light and electrical currents are combined. It detects and emits electromagnetic radiation within the spectrum’s visible and near-infrared regions (NIR). 

This technological field is seen to be fast emerging as it allows devices to source, detect, and even control light. It can include electrically driven light sources such as light-emitting diodes and laser diodes, components for converting light to an electrical current like solar and photovoltaic cells, and devices that can electronically control light propagation.


How does an Optoelectronic work?

The underlying mechanisms of optoelectronic devices are based on the emission of electrons by photons. It is where light strikes a photoelectric material and is formally known as the photovoltaic effect; There is a crystal lattice that absorbs python energy with the help of the electrons inside. However, the material will have to release any energy surplus, and the same concept applies to the production of light by optoelectronic devices. 


Types of Optoelectronic Devices and Their Applications

Optoelectronics is very versatile as it uses light and electricity, necessities vital in every sector like military services, automatic access control systems, telecommunications, medical equipment, and more. Nowadays, some optoelectronic devices have semiconductors like silicon (Si) in their properties. There are still distinctions when identifying electronic components of these categories, but their fusion produces products and solutions for consumer, industrial, and military sectors.

The following are the different types of optoelectronics:

Here are the specifications of each type corresponding to the figure numbers above: 


  • Light-Emitting Diodes (LEDs)
An electroluminescence effect occurs, producing photons when electrons and holes are combined. 
  • Photodiodes
A light sensor semiconductor with building blocks known as an active P-N junction generates a current when light falls.
  • Photoresistors
These are light-controlled resistors; hence, they are also referred to as light-dependent resistors or LDRs. 
  • Photovoltaics
This converts the sun’s energy into electricity and may also be called solar cells.
  • Fibre Optics
A device used with optoelectronic for transmitting information through light modulation like sensors produced by Infineon Technology, Amphenol, Analog Devices, and more!
  • Encoder Sensor
    Integrated Circuits  
A complete system-on-chip (SoC) integrated circuit sensor converts linear motion to electrical signals for rate, velocity, speed, distance, direction, and position. 

  • Laser Diodes
A semiconductor is quite similar to that function of LEDs, but it is 70x more efficient. It is also known as Vertical Cavity Surface Emitting Laser (VCSEL).


Who manufactures and offers Optoelectronic components?

Aside from identifying electronic components, it is also essential to know where to get them and who makes them available in the market. As the electronic industry evolves, components can become obsolete and difficult to find. This is why BD Electronics exists to make the impossible possible! We do not produce optoelectronic components; instead, we will supply them to you according to your needs and preferences from all these electronic manufacturers.
