DESCRIPTION:Speaker: William Hease\nhosted by Johannes Fink\nAbstract: The 
 field of optomechanics aims at exploring the coupling between optical and 
 mechanical degrees of freedom on systems of varying type and scale. It has
  been developing rapidly in the last 15 years\, with a wide variety of sys
 tems showing optomechanical coupling.\nThe works presented focus on  Galli
 um Arsenide (GaAs) nanoscale disks placed in a cryogenic environment (2.7 
 K). A major goal is to make use of the optomechanical coupling to cool the
  system further (to ~50mK)\, so as to reach the so-called quantum regime\,
  where the mechanical degree of freedom has less than one quantum of excit
 ation.\nIn order to enhance optomechanical cooling\, resonators quality fa
 ctors and optomechanical coupling constants must be maximized. Various opt
 imizations brought to the fabrication of GaAs optomechanical micro disks a
 nd to experimental techniques will be developed.\nSome other works involvi
 ng GaAs optomechanical disks will also be briefly presented.
