摘要： Arrangements using air trench cladding enables minimization of the evanescent tail to suppress light coupling to radiation modes, resulting in low-loss bends and splitters. Structures including sharp bends and T-splitters without transmission loss, crossings without crosstalk, and couplers from/to fibers and with out-of-plane waveguides without substantial loss are provided with such air trench claddings. Air trench sidewall cladding of waveguides pushes evanescent tails toward top and bottom claddings to enhance coupling between vertically positioned waveguides. Fabrication processes using wafer bonding technology are also provided.

摘要： An optical device includes a first and a second splitting device. Each of the first and second splitting devices have respective first and second input ports, respective first and second output ports, and a respective transfer matrix. A first optical waveguide is optically coupled to the first output port of the first splitting device and the first input port of the second splitting device. A second optical waveguide is optically coupled to the second output port of the first splitting device and the second input port of the second splitting device. The first and second optical waveguides are configured to introduce a phase shift of π radians to the optical radiation propagating through the first optical waveguide with respect to the optical radiation propagating through the second optical waveguide. The transfer matrix of the second splitting device is the diagonal transpose of the transfer matrix of the first splitting device and the transfer matrix of the second splitting device is substantially different from the transfer matrix of the first splitting device.

摘要： A high speed sampling technique is proposed using a cascade of optical waveguide interferometers driven by CW sinusoidal traveling or standing microwaves. Each interferometer multiplies the optical signal by a function closely approximated by cos.sup.4 .omega.t, where .omega. is the frequency of its microwave drive. A cascade of four interferometers with 2.6 V microwave drives at 10, 20, 40, and 80 GHz and a total length of 2 cm can sample an optical signal with 2 ps resolution and 50 ps between samples.

摘要： A surface acoustic wave (SAW) device including a crystal substrate having two substantially planar surfaces and at least one SAW-to-plate mode coupler positioned on one of the surfaces. The SAW-to-plate mode coupler includes a plurality of parallel, linear surface perturbations. The surface perturbations are adapted to convert a portion of an incident SAW to a bulk acoustic wave (BAW). In addition, the coupler is adapted to convert a portion of an incident BAW (from the crystal bulk region) to a SAW at those surface perturbations. In addition, the planar surfaces of the crystal substrate are adapted to reflect portions of incident BAW's. The coupler is positioned with respect to the crystal characteristics so that SAW's and BAW's resonantly interact at the coupler. In alternative configurations, a second SAW-to-plate mode coupler is positioned on the second surface of the crystal substrate. This second surface coupler also is adapted to convert a portion of an incident SAW to a bulk acoustic wave (BAW) at a plurality of parallel surface perturbations, and to convert a portion of an incident BAW to a SAW at those perturbations. The couplers are positioned in view of the crystal characteristics so that the BAW's and SAW's resonantly interact at the couplers.
