Abstract
HBr/HNO3/H2O etching solutions have been extensively investigated regarding their properties for submicrometer patterning of III-V compound semiconductors. The chemical behaviour of the solution itself was clarified and the etching properties and mechanism were investigated. High quality gratings for Dynamic Single Mode (DSM) Laser were fabricated and extremely pure emission spectra have been recorded.
