    Abstract: A tunable microfluidic device (200) incorporating a ring resonant cavity comprises at least one optical resonant cavity (202) having a microfluidic channel (204) disposed through its center, an input waveguide (208), and an output waveguide (210). A fluid having a pre-selected refractive index is passed through the microfluidic channel (204). The presence of fluid passing through the center of the cavity waveguide (202) modifies the optical propagation characteristic of cavity waveguide. By introducing a fluid into the cavity, the resonant property or condition is changed such that the cavity waveguide (202) will resonate at a different frequency of wavelength. This flexibility allows the resonator to be tuned to a desirable frequency or wavelength to facilitate optical switching and filtering

    Abstract: An optomechanical device, based on mode coupling, and methods for its use. Two waveguides (190,200) cross each other and a movable suspended coupler is located at the cross-over, such that on activation, the light propagating in one of the waveguides is coupled into the second waveguide. The coupler (210) may be a third waveguide that upon in-plane deflection, is brought into close proximity or to contact with the sides of the two waveguides. This action creates an optical path by means of the evanescent fields of the two waveguides and the coupling waveguide itself. This basic building block creates a 1 to 1 switching unit that can be scaled up to form non-blocking matrices of 'n' input waveguides by 'm' output waveguides. Applications for Wavelength Add and Drop Systems, and for Gain Equalizer Systems are described.

    Abstract: Methods of tuning, switching or modulating, or, in general, changing the resonance of waveguide micro-resonators. Changes in the resonance can be brought about, permanently or temporarily, by changing the size of the micro-resonator with precision, by changingthe local physical structure of the device or by changing the effective and group indices of refraction of the mode in the micro-resonator. Further changing the asymmetry of the index profile around a waveguide can alter the birefringence of the waveguide and allows one to control the polarization in the waveguide. This change in index profile may be used to change the polarization dependence or birefringence of the resonators.

    Abstract: Devices utilize elements carried by a fluid (4506) in a microchannel (4504) to switch, attenuate, shutter, filter, or phase shift optical signals. In certain embodiments, a microchannel carries a gaseous or liquid slug that interacts with at least a portion of the optical power of an optical signal traveling through a waveguide (4510, 4512). The microchannel may form part of the cladding of the waveguide, part of the core and the cladding, or part of the core only. The microchannel may also have ends or may be configured as a loop or continuous channel. The fluid devices may be self-latching or may be semi-latching. The fluid in the microchannel is moved using e.g., electrocapillarity, differential-pressure electrocapillarity, electrowetting, continuous electrowetting, electrophoresis, electroosmosis, dielectrophoresis, electrohydrodynamic electrohydrodynamic pumping, thermocapillary, thermal expansion, dielectric pumping, and/or variable dielectric pumping.
