Key Points

The study aims to simplify the fabrication process of second harmonic generation (SHG) devices using AlN/AlGaN superlattices.
Grew AlN/AlGaN strained-layer superlattices (SLS) to create waveguides.
Measured wavelength spectra and power dependency of the generated light.
Successfully demonstrated far-UV emission from the SLS structure.
Confirmed the absence of polarity inversion in the SLS design.

Abstract

The primary purpose of growing AlN/AlGaN SLSs was to simplify the SHG device fabrication process. The wavelength spectra and power dependency confirms the first successful demonstration of far-UV emission from a polarity-inversion-free SLS structure.
