Abstract

Photonic materials suitable for the mid-infrared wavelength range are in high demand for future astronomical instruments, particularly for space missions like the Large Interferometer For Exoplanets (LIFE). In this work, we have developed a high-performance photonic integrated platform with the potential to operate in the entire wavelength range required by the LIFE mission (6-16 μm; goal: 4–18.5 μm). Buried InGaAs waveguides with InP cladding are used, with wet-etch fabrication patterning and Fe doping incorporation during material growth. Thanks to these approaches, the first experimental results demonstrate remarkably low propagation losses below 2.5 dB/cm at 9.5 wavelengths in both TE and TM polarization modes. The achieved results of this new platform are the starting point for more complex photonic devices including nulling beam-combiners among other astronomical applications.
