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 approximately 120 K. They employ the quantum cascade scheme based on interminiband transitions in graded superlattices and are realized in the InGaAs/AlInAs material system.
