Polymer and Silicon Nitride Integration Platforms

Fraunhofer HHI offers hybrid photonic integrated circuits tailored towards their specific application from VIS to NIR.

The polymer and silicon nitride platforms of Fraunhofer HHI are specifically suitable for actives passives integration. Photonic building blocks including ring resonators, MMIs, AWGs, tunable gratings and phase shifters are available. The micro-optical bench allows for on-chip integration of polarization & wavelength handling elements as well as optical isolators, circulators, and nonlinear crystals for quantum technologies.

Plug and Play PIC Evaluation with PIConnect

Fraunhofer HHI has developed PIConnect, a new PIC evaluation setup with integrated laser drivers, current and voltage sources. The system enables parallel operation of the building blocks and, thus, convenient evaluation of PICs. A mainboard with 8 current & voltage sources, 4 laser drivers and a temperature controller is combined with a microcontroller board and a temperature controllable PIC board. This evaluation setup simplifies the handling and characterization of PICs and lowers financial investment at an exploration stage. PIConnect is available as an additional offer to Fraunhofer HHI´s technology platforms.

High-Speed Electro-Optic Modulators and more

High-speed electro-optic phase shifter, fiber-spot size converter, thermo-optic phase-shifter, on-chip resistor, and other building blocks on thin-film lithium-niobate for Mach-Zehnder modulator based PICs.
