In semiconductor quantum wells, photoelastic interaction is increased by several orders of magnitude at the exciton resonance frequency, making them promising for optomechanics [1]. Under resonant laser pump, the exciton-mediated stimulated Raman scattering leads to controllable sound amplification or attenuation, akin to the optomechanical heating and cooling effects.… Read the rest
