Abstract :
The longest wavelength whispering gallery semiconductor disk lasers fabricated to date are reported. The devices operate at λ≃16 μm up to a temperature of ~120 K. They employ the quantum cascade scheme based on interminiband transitions in graded superlattices and are realised in the InGaAs/AlInAs material system
