Abstract :
Quantum cascade laser sample microdisks with double plasmon waveguiding were fabricated (lambdasime80 mum). High impedance mismatch between the confined optical mode and surrounding free- space allows the existence of whispering gallery modes ´unobtainable´ in standard dielectric microdisks.
