Very long wavelength (lambda similar or equal to 16 mu m) whispering gallery mode microdisk lasers
17 February 2000
The longest wavelength whispering gallery semiconductor disk lasers fabricated tc date are reported. The devices operate at lambda similar or equal to 16 mu m up to a temperature of similar to 120K. They employ the quantum cascade scheme based on interminiband transitions in graded superlattices and are realised in the InGaAs/AlInAs material system.
