Metal-assisted chemical etching of III-V semiconductors for advanced optoelectronic device fabrication
… the fabrication of InGaAsP gratings for distributed feedback (DFB) lasers by MacEtch as well as antireflection textured GaAs photodiodes incorporating graphene quantum dots (GQDs). MacEtch behavior of InGaAsP in H2SO4 and H2O2 is dependent on the crystal orientation and material of the …

Design and characterization of semiconductor laser structures for hydrogen sensing applications
… several platforms in which semiconductor lasers can be functionalized to detect hydrogen concentrations below the lower explosive limit have been developed. The laser structures were chosen such that there already exist well-established fabrication technologies, and the functionalization …
