Seren Photonics logoUK-based Seren Photonics has successfully completed the first tranche of a £1 million investment round with funding from existing and new investors. Seren says that these funds will be used to continue the manufacturing scale-up of its template technology along with the further development of green LED epitaxy structures.

Seren develops a suite of long wavelength LED epitaxy on its novel semipolar GaN aimed at delivering higher efficiency and more color stable green, yellow and red devices. Seren says that its Semipolar enabled LEDs overcome shortcomings of green LEDs manufactured on polar GaN, mainly low wall plug efficiency and poor poor wavelength stability over a range of current densities.
