Optoelectronics

Intro

Optoelectronic devices are products relating to the detection or creation of light. Chances are you deal with optoelectronics quite often, whether it’s in the form of LEDs in remote controls, solar panels, or fibre optic broadband.

Optoelectronic devices

A lot of markets utilise optoelectronics, namely military, consumer and industrial.

Laser radars, optical sonar systems, night vision equipment that uses infrared are all integral applications of optoelectronics for the military. There is also optoelectronics tech utilised for communication systems, both in military and consumer products.

Optoelectronics all work on the principle of the photovoltaic effect. This is when electrons are ejected from the material, creating electrical signals. This can also work the opposite way when components can use electricity to generate light.

It can only detect or emit certain waves of electromagnetic radiation, usually either visible light or near-infrared (NIR).

Advantages

The utilisation of optoelectronic components in the satellite industry has meant advancement in design. Satellite-to-satellite communication could one day happen with lasers. Solar cells also convert solar energy into electrical power, which could be the power source for large satellites one day.

Optoelectronics is already integral to the communications industry. Optical fibre communication systems is sometimes called one of the “greatest engineering achievements of the past century”. Need I say more? Well, I will. Optoelectronics was at the root of both high-quality voice communication and the internet. If that doesn’t prove how advantageous it is I, don’t know what will.

Disadvantages

Optoelectronics are temperature sensitive. As a result, at extreme temperatures components and circuits are at risk of damage. For applications including CMOS sensors, digital light processors and optical transceivers, a thermoelectric cooler has to be implemented.

Precise alignment is needed for coupling, too, as well as the difficulties that come with integrating optoelectronic devices on a substrate. All of these are potential deterrents from using the devices.

Market predictions

In 2020 the market was valued at $5.14 billion, increasing to $9.83 billion by 2026 at a 10.25% CAGR.

The surge is, in part, predicted due to the increase in electric vehicles (EVs) in production, which is forecast to continue. LED displays are now more common than ever, with even wearable tech featuring high-definition screens.

According to Market Insight Reports optoelectronics market expected to grow at a CAGR of 10.25% over the forecast period of 2019 to 2024.

As with many areas of electronics, the possibilities for advancement are endless. Especially in relation to satellites, the future may hold great things.

Demand Electronic Components

Keeping pace with high power terminal block demand

High power terminal block demand is soaring with the buildout of EV charging infrastructure. The reason is simple – high current requires high power terminal blocks, making these components essential for EV charging stations.

The rapid growth in the adoption of electric vehicles is fuelling demand for high power terminal blocks beyond what most people expected.

The UK Government’s decision to ban petrol and diesel cars from 2030 has accelerated the buildout of EV chargers, leading to significant new investment by leading companies like Tesla and BP Chargemaster. There are now more than 35,000 charge points across the UK, a figure that is expected to increase by 10,000 in 2021.

The big barrier to purchase with electric vehicles is a lack of charging infrastructure and slow charge times. Building more charging stations is the simple solution to this problem, but bigger, better high power terminal blocks are also needed for the next generation of rapid chargers that will provide power up to 350 kW.

What is ‘high power’?

Anything above 40 amps is classed as high power. All public electric charging stations significantly exceed this amount. High power terminal blocks are typically available up to 125 amps and higher for custom applications.

We need terminal blocks capable of handling higher currents when the charging speed demand increases for the station. EV chargers are classified in three categories: Level 1, Level 2 and direct current. Whether a charger is AC or DC, the higher the current, the higher the power draw, so the more robust the terminal needs to be.

Terminal block specifications

Terminal blocks serve as a routing tool for wiring. They are simple components, used to connect circuits together and provide an electrical ground for the circuit.

Screw terminal, push button and push-in terminal block styles are available. These accommodate different types of circuit design. The module type can be interlocking or single-piece with a plug or receptacle housing.

Terminal blocks for EV charging stations are optimised for this specific purpose and they are normally rated for at least 150% of the max current.

Meeting the soaring demand for high power terminal blocks

Unlike semiconductors, there is no immediate shortage of high power terminal blocks. They are available in the tens of thousands per order.

There is competition between the EV and renewable energy industry for high power terminal blocks though. Both industries are significant consumers of these components and demand is increasing with new electrical installations.

Other in-demand components for electric vehicle charging infrastructure include battery connectors and high voltage connectors designed to handle the heat of EV charging. These connections need to be small but also thermally efficient.
