Abstract: Integrated optical devices include various configurations of active optical switches and other passive components such as splitters that are useful for controlling signals in optical data transmission networks. An optical switch may be used to switch light between waveguides on different substrates. The active optical switch may include one or more microfluidic droplets that are controllably movable relative to the coupling region to change the amount of light couplable between the first and second switch waveguides. Different configurations of the droplets can be controlled for operating the switch in different switching states. An optical switch can be included in an end use transceiver device for remotely controlling an optical time domain measurement. A microfluidic switch can be used to control wavelength-selective reflection in a waveguide reflector.

Abstract: A photonic integrated circuit is presented that includes a substrate, and a first and second waveguide patterned on the substrate. The first waveguide guides an input beam of radiation. The photonic integrated circuit also includes a coupling region, wherein the first and second waveguides each pass through the coupling region. One or more modulating elements are coupled to each of the first and second waveguides. The first waveguide and the second waveguide have a first facet and a second facet, respectively, and first and second reflections are generated at the first and second facets within the first and second waveguides, respectively. The one or more modulating elements coupled to each of the first and second waveguides are designed to adjust the phase of the first and second reflections before the first and second reflections pass through the coupling region.

Abstract: A composite optical waveguide is constructed using an array of waveguide cores, in which one core is tapered to a larger dimension, so that all the cores are used as a composite input port, and the one larger core is used as an output port. In addition, transverse couplers can be fabricated in a similar fashion. The waveguide cores are preferably made of SiN. In some cases, a layer of SiN which is provided as an etch stop is used as at least one of the waveguide cores. The waveguide cores can be spaced away from a semiconductor layer so as to minimize loses.

Abstract: An integrated circuit includes an optical reflector with one or two bus optical waveguides and a one-dimensional, photonic crystal nanobeam cavity to provide single-mode reflection with a narrow bandwidth. In particular, the nanobeam cavity may be implemented on a nanobeam-cavity optical waveguide (such as a channel or ridge optical waveguide), which is optically coupled to the one or two bus optical waveguides. The nanobeam-cavity optical waveguide may include notches along a symmetry axis of the nanobeam-cavity optical waveguide that are partially etched from edges of the nanobeam-cavity optical waveguide toward a center of the nanobeam-cavity optical waveguide. Furthermore, a fill factor of the notches may vary as a function of location along the symmetry axis, while a pitch of the notches is unchanged, to define the nanobeam cavity.
