Abstract: An optical modulator that uses adiabatic tapers to change the width of the waveguides between multimode waveguides and single mode waveguides on a low-loss, e.g. thin-film lithium niobate, electro-optic platform. The architecture enables the utilization of the fundamental mode of multimode wide optical waveguides that have lower optical propagation loss without sacrificing the benefit of the signal integrity and ease of control of single mode operation.

Abstract: A system and method is provided for attenuating a light signal. One embodiment includes a method for causing optical attenuation in a waveguide, where the waveguide has an input port for receiving a light signal and an output port for output of an attenuated light signal. First, an electric field is generated in at least a portion of the waveguide, such that a first refractive index in that portion of the waveguide is changed to a second refractive index. Next, the light signal in the waveguide is directed from the input port to the output port through the electric field. And lastly, the light signal is attenuated as a function of the electric field. The light signal may be attenuated, for example, by changing the deflection angle, changing the beam collimation width or from emitting part of the light signal from the waveguide before the light signal reaches the output port.

Abstract: An alignment device includes an alignment member with one or more waveguide-alignment grooves, resonator alignment grooves, and/or an alignment groove for a second optical element such as a modulator. The various alignment grooves reliably establish and stably maintain evanescent optical coupling between the optical elements positioned therein. A method for assembling a resonant optical power control device may include: fabricating an alignment member with the alignment grooves; positioning and securing the optical elements in corresponding alignment grooves for optical coupling therebetween. Alignment grooves in the substrate and/or in one or more of the optical elements are fabricated at proper depths and positions and preferably with mating grooves and/or flanges to enable optical coupling without extensive active alignment procedures.
