ABOUT US

What We Do

Yelo is a leading manufacturer of automated test equipment for the Photonics and Electronics industries. We are UK based (in Northern Ireland), founded in 1983 and have a team of  40 including; Electronic engineers, mechanical design engineers, software developers and test/commissioning/support engineers. Our biggest markets are USA, Asia and Europe. To date we have over 300 test systems installed internationally - and continue to grow this figure.

We specialise in manufacturing equipment that tests the reliability of laser devices which are used in Photonic Integrated Circuits (PIC's). These laser devices are used in Data Centers and in Telecommunications to carry information. 

Yelo build equipment to stress the laser devices using a process called burn-in. We then test the functionality of the lasers to make sure they still work and to screen out (remove) any defective laser devices  from reaching the field. 

The equipment is designed to test lasers in high volumes so that device manufacturers in production environments can scale up and meet the high volume demands of the market. Alternatively, the equipment can be customised to test laser devices in low volumes for device manufacturers operating in low volume R&D environments.


 

Our Systems

The Main Tests that are systems perform are:

LIFE TEST -
Used to predict the laser diode life expectancy under the intended operating characteristics.

BURN-IN TEST -
Used to identify and remove any defective laser diodes at an early stage which prevents infant mortality at the post production stage.

Our Services

Our Services Include:

CONTRACT LASER SERVICES -
For companies that cannot invest the capital into purchasing one of our testing systems, we offer laser diode testing on a contract basis, with an option to buy a system in long term. With our contract testing service, you can send your laser device to us where our experienced engineers will perform the tests your require and record the data for you.

Our Story

Yelo have been manufacturing laser testing equipment for over 30 years and have built up a strong reputation as the experts and innovators in the field of laser testing. With several changes of name over the years and a few management buyouts, it's been quite a story to how we got to this stage. Have a look at the Brand Timeline below.

We Are Growing

The reason why we have been in business for so long and why we keep growing is because laser diodes are becoming more powerful and are also becoming smaller, so our testing equipment helps to screen out any failed or low quality laser diodes and guarantees reliability and quality for your product in post production use.

We have our biggest markets in China, with a support office now set up in Shanghai.
