摘要

Recent advances in semiconductor film deposition allow for the growth of heavily-doped germanium with effective plasma frequencies above 60 THz, corresponding to wavelengths below 5 μm. This technology paves the way for mid-infrared nanoplasmonics with application in integrated telecommunication systems and enhanced molecular sensing in the so-called vibrational fingerprint spectral region [1]. In this work, we demonstrate that Ge antenna structures are also suitable for nonlinear optical processes such as third harmonic generation (THG) in the mid infrared [2], owing to the strong resonant enhancement. Subwavelength-confined light emitters are of high interest for experiments targeting single molecules or other isolated quantum systems [3].
