Etched mirror lasers offer the possibility of being integrable in Opto-Electronic Integrated Circuits (OEIC). A versatile processing technique of GaAs/AlGaAs Wet Chemically Etched Mirror Lasers (WCEML) has been developed previously. It is applicable to all laser structures in the InGaAs/AlGaAs/GaAs system. A special set of masks allowed us to vary the cavity lengths of ridge waveguide type devices from 750 /spl mu/m down to 11 /spl mu/m and ridge widths of 4, 6 and 10 /spl mu/m. The processing requires four photolithography steps. In this paper we report on the results obtained from four different GRINSCH laser structures: one having a bulk GaAs active layer (50 nm thick) while the others have 2, 3 and 5 QWs of 7 nm GaAs as an active layer respectively.
