“…It should be pointed out that, in the study of TM modes for control of radiation pressure on mirrors, Mizrahi and Schächter also found the intrinsic light-speed point on a TM mode in their matching-layer Bragg reflection waveguide structure, where the lower-index layers (instead of the higher-index layers) are adjacent to the guiding region [29], while such an intrinsic lightspeed point is only on the TE mode in this paper, as shown in Fig. 6.…”

Abstract-Numerical results are presented for single-mode guidance, which is based on photonic band gap (PBG) effect, in one-dimensional planar all-dielectric light-guiding systems. In such systems there may be two kinds of light-speed point (the intersection of a mode-dispersion curve and the light line of guiding region ambient medium): One is the intrinsic light-speed point that is independent of the guiding region width, and the other is the movable light-speed point that varies with the guiding region width. It is found that the intrinsic lightspeed point plays an important role to form the single-mode regime by destroying the coexistence of the lowest guided TM and TE modes that are born with a degeneration point. A mode-lost phenomenon is exposed and this phenomenon suggests a way of how to identify PBGguided fundamental modes. Quasi-cutoff-free index-guided modes in the PBG guiding structures are examined, which appear when the higher-index layers are adjacent to the guiding region and the guiding region width is small. The transverse resonance condition is derived in the Maxwell optics frame, and it is shown that there is a significant revision to the traditional one in the ray optics model. A sufficient and necessary condition for intrinsic light-speed points is given, which provides strong support to the numerical results.

“…This force finds important use in optomechanical circuits since the force can be generated along the transverse direction of a waveguide without the need for making a bend or suffering loss. In submicron scale photonic waveguides, the gradient of an optical field is enhanced by orders of magnitude due to the strong field confinement, as theoretically predicted by Povinelli et al [67,68]. It is also not necessary to employ a cavity to obtain strong force.…”

Chip-scale optomechanical resonators have the advantage of higher Q values, smaller dimensions, and thus a greater potential for scalability and device control. This chapter discusses further integration of chip-scale optomechanic elements on a circuit level. Circuit integrated optomechanics brings a range of additional benefits for both fundamental studies and practical device applications of optomechanics. It takes advantage of many circuit components that have been developed by the nanophotonics community, such as grating couplers, splitters, combiners and low loss waveguides, which can be directly utilized to form scalable circuits for routing optical signals. High quality photonic resonators and band-gap structures, such as microring, microdisk, and photonic crystal nanocavities, can be seamlessly embedded in the circuit for direct interfacing with nanomechanical resonators without suffering from significant optical loss. Homodyne detectors, such as Mach-Zehnder interferometers, are implemented directly as part of the circuit to achieve sensitive, alignment free measurement of mechanical motion. Circuit optomechanics not only leads to further scaling of optomechanical systems but also brings new interaction dynamics in light-mechanics coupling. We will discuss the various radiation dynamics and non-radiation dynamics that are present in circuit optomechanical systems. Integrated Optomechanics and Optomechanical CircuitsLately we have witnessed rapid progress in cavity optomechanics with demonstration of dynamic back-action cooling and amplification of mechanical structures of vastly different length scales. In particular, chip-scale optomechanical resonators

“…Generally, force densities on dielectrics may be viewed as resulting from two processes [13,21,22]: (1) the interaction of effective polarization volume current densities with the magnetic field, and (2) the interaction of polarization surface charge densities with the electric field. In the TE case, no component of the electric field is perpendicular to the boundaries of the dielectrics, and therefore no polarization surface charge densities are formed.…”

“…For instance, light guided between two waveguides or mirrors creates a repulsive force for an antisymmetric transverse field and an attractive force for a symmetric transverse field [12,13]. Moreover, a superposition of a symmetric and antisymmetric modes may hold the waveguide in a stable equilibrium [13,15,17]. Such phenomena can be experimentally observed in nanomechanical devices fabricated on a chip, as was recently demonstrated with a suspended silicon waveguide [18].…”

Self-alignment and instability of waveguides induced by optical forces

et al. 2009

We introduce a new fundamental property of waveguides induced by the forces of the guided light, namely, the ability to self align or be in instability. A nanoscale waveguide broken by an offset and a gap may tend to self align to form a continuous waveguide. Conversely, depending on the geometry and light polarization, the two parts of the waveguide may be deflected away from each other, thus being in an unstable state. These effects are unique as they rely on the presence of both the guided mode and the scattered light. Strong self alignment forces may be facilitated by near field interaction with polarization surface charges.
