Abstract :
Summary form only given. There is a strong interest in the use of quantum cascade lasers based on intersubband transitions operating at room temperature in the mid-infrared for sensing applications. Our electrically tunable quantum cascade laser uses a design based on a three well active region. It is grown by molecular beam epitaxy using InGaAs and AlInAs alloys lattice matched on an InP substrate.
