Photonic integrated circuits: the next frontier of advanced optoelectronic devices

August 31, 2026 -

Design, simulation and manufacturing advances continue to push photonic integrated circuits (PICs) to smaller sizes, which provide greater capabilities per chip, writes Liam Critchley.

Advanced optics and photonics where light is manipulated and transmitted has already revolutionised communications through optical fibres and amplifiers. PICs are the next frontier of advanced photonic systems and are much smaller than many other optical systems. PICs are essentially the photonic equivalent of very small electronic semiconducting chips and are getting smaller and more advanced as their development continues.

What are PICs?
