Lithium niobate on insulator (LNOI) is a very promising PIC platform with a high electro-optic coefficient, enabling low-power and high-speed modulation, perfect for datacom needs.
The latest module, assembled by PHIX for the LOLIPOP project, showcases the power of this technology. Built on an LNOI chip fabricated at CSEM’s TFLN foundry, it features 5 high-speed modulators operating at a 1550 nm wavelength. The package, which included wirebonding to a PCB designed by imec, and hybrid integration with a silicon nitride (SiN) spot size converter chip by LioniX International, achieved sideband modulation frequencies of over 40 GHz with remarkably low optical losses.
Through LOLIPOP, PHIX is committed to advancing the industrialization and commercialization of heterogeneous integration processes, combining the best of multiple PIC platforms.
