Summary form only given. We address practical issues involving quantum cascade laser (QCL) fabrication, introduce a new fabrication technique which permits a reduction in the waveguide width which is simple to implement, and report on quantum cascade devices lasing at /spl lambda/=5 /spl mu/m fabricated using this new scheme. The QC wafer, based on the design demonstrated by Faist et al. (1996), was grown in-house. Production of QC lasers with reduced threshold currents are envisaged through a reduction in the laser waveguide core width.
