Abstract

A single-slot waveguide for transverse electric (TE) to transverse magnetic (TM) mode conversion operating at wavelengths around 2 μm is proposed based on an InGaSb/AlGaAsSb quantum well structure. The polarization mode convertor has a deep-etched ridge waveguide and a single shallow-etched slot, and can be fabricated in a single stage of dry-etching. The dependence of polarization conversion efficiency on slot width, slot position, slot depth and waveguide length was investigated, and a design that was insensitive to fabrication tolerances was identified. A TE-TM mode conversion efficiency of more than 97% can be obtained in a 2141-μm-long waveguide.
