                  Abstract
                  Two mirrors guiding laser light may experience an either 
                  attractive or repulsive force, according to the type of 
                  eigenmode they guide. We propose a method for the control over 
                  the motion of a mirror by changing the operation wavelength 
                  along the dispersion curve of the mode. In addition, a novel 
                  method for trapping a mirror in a stable equilibrium, based on 
                  a superposition of two modes, is presented. The mirror is then 
                  trapped by being exposed to light only from one of its sides.
