Using a state-of-the-art glass micro-chip fabrication platform involving femtosecond laser inscription, Modular Photonics has developed market-leading mode-selective devices. This breakthrough technology offer compact ‘plug and play’ solutions to the challenge of addressing different modes in an optical fibre. The technology can be used in applications ranging from data centres to long-haul telecommunications.

The technology is made possible by the three-dimensional capability of the femtosecond laser direct-write technique used. This allows for intricate waveguide structures to be realized that would otherwise not be possible using planar technology.
