Abstract: The gallium nitride material family offers an attractive platform to extend the application range of integrated photonics down to wavelengths in the blue and ultraviolet spectral range. Simultaneously, it allows the integration of light sources such as LEDs and lasers with waveguides and meta-optics to gain complete control over all dimensions of light. To this end, not only is control over the dimensional properties of nanophotonic structures necessary, but flexibility in the refractive index of involved materials is also highly beneficial. Nanoporous gallium nitride fabricated and structured by ion implantation and electrochemical etching can provide this versatility. In this contribution, we report on nanoporous gallium nitride as a novel material in integrated photonics and discuss devices and technological boundary conditions.
