Paper Abstract

Laser refrigeration of solids is a promising technology capable of remotely removing heat from a small active device with minimum expended energy. The most critical factors limiting performance of laser cooler are low quantum efficiency and trapping of fluorescence inside the cooling volume due to total internal reflection. This issue becomes especially pressing in semiconductors due to their large refractive index. In this work we explore two new methods of improving the refrigeration efficiency - using type II quantum wells and using surface plasmon polaritons.
