In this PhD thesis, the nano-opto-mechanical system (NOMS) is explored and two nano-opto-mechanical devices are designed, analyzed, simulated and fabricated. Firstly, an angular momentum generator consisting of a ring resonator, a wave guide and a group of nano-rods is designed, theoretically analyzed and simulated. The theoretic alanalysis and numerical results show that a series of rotating optical field (ROF) are generated when different resonant wave lengths are coupled into the generator. Subsequently, the optical force, the optical potential and the optical torque of the generated ROF are theoretically analyzed, numerically simulated and discussed. The optical force distributions are affected by the ROF with different angular orders and different objects. The optical torques are analyzed and discussed for different objects, i.e. spherical nano-particle, nano-wire and nano-rotor. Finally, a tunable coupled-resonator-induced transparency (CRIT) system, which is driven by the optical force between the ring resonator and the substrate, is designed, theoretically analyzed, simulated, fabricated and experimented. The tunable CRIT system consists of a bus wave guide and two coupled ring resonators, in which one is the released ring and the other is the fixed ring. Different input powers produce different optical forces on the released ring, which produce different final deformations, change the optical field buildup, shift the transmission spectrum and vary the group delay
