Abstract :
The authors present a new cavity cooling mechanism in semiconductors due to an optical excitation of carriers above the bandgap and the stress that these carriers introduce in the crystal lattice. The new method proves very power efficient and could potentially help in enabling ground state cooling of vibrational modes of semiconductor resonators. A laser cooled narrow-band phonon bath may open up a new avenue for photonics.
