Annotation	We address the problem of the stochastic particle transitions between stable positions in a one-dimensional periodic potential profile. With respect to the experimental realization such stable positions are represented by the optical traps formed in a standing wave. The behavior of sub-micrometer sized particles in this "optical potential energy landscape" is analyzed theoretically and experimentally and the stress is put on the particles jumps between the neighboring optical traps. Our theoretical model assumes over-damped stochastic motion of a particle in a finite-depth potential well. Subsequently, Mean First Passage Time is utilized to express the new quantity called the Mean Optical Trap Escape Time (MOTET) that describes the mean time of the particle escape to a neighboring stable position (optical trap).
