Company Profile

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.
