Summary form only given. Photonic devices operating in the mid-IR (3 μm to 13μm wavelength range) are of great interest for a wide range of applications, such as free-space communications, environmental monitoring or defence. Group IV-based material platforms [1], such as silicon-on-insulator (SOI)[2] and silicon-on-sapphire (SOS)[3] have attracted significant interest for mid-IR integrated photonics. However, absorption in silica beyond 3.5 μm and in sapphire beyond 5.5 μm eventually limits...[Show more]
