Abstract: An optical device includes a first waveguide having a longitudinal axis and a first end facet inclined at a non-normal angle to the longitudinal axis, and a second waveguide, which has a second end facet and is fixed with the second end facet in proximity to and parallel with the first end facet. An actuator is coupled to move the first end facet of the first waveguide in a direction transverse to the longitudinal axis between a first position in which a distance between the first and second end facets is less than 25 nm, and a second position in which the distance between the first and second end facets is greater than 300 nm.

Abstract: A routing controller (30) includes an interface (68) and multiple processors (60). The interface is configured to receive a permutation (76) defining requested interconnections between N input ports and N output ports of a Benes network (24). The Benes network includes multiple 2-by-2 switches (42), and is reducible in a plurality of nested subnetworks associated with respective nesting levels, down to irreducible subnetworks including a single 2-by-2 switch. The multiple processors are configured to collectively determine a setting of the 2-by-2 switches that implements the received permutation, including determining sub-settings for two or more subnetworks of a given nesting level in parallel, and to configure the multiple 2-by-2 switches of the Benes network in accordance with the determined setting.

Abstract: A tunable vertical-cavity surface-emitting laser (VCSEL) is provided. The VCSEL includes a VCSEL emission structure, piezoelectric material, and a piezoelectric electrode. The VCSEL emission structure includes a first reflector; a second reflector; and an active cavity material structure disposed between the first and second reflectors. The active cavity material structure includes an active region. The piezoelectric material is mechanically coupled to the VCSEL emission structure such that when the piezoelectric material experiences a mechanical stress, the mechanical stress is transferred to the active cavity material structure of the VCSEL emission structure. The piezoelectric electrode is designed to cause an electric field within the piezoelectric material. The electric field causes the piezoelectric material to experience the mechanical stress, which causes the active cavity material structure to experience the mechanical stress, which causes the emission wavelength of the VCSEL to be modified from a nominal wavelength of the VCSEL.

Abstract: An optical switching device (20) includes a substrate (39) and first and second optical waveguides (23, 25) having respective first and second tapered ends (62, 64), which are fixed on the substrate in mutual proximity one to another. A pair of electrodes (36, 38) is disposed on the substrate with a gap therebetween. A cantilever beam (32) is disposed on the substrate within the gap and configured to deflect transversely between first and second positions within the gap in response to a potential applied between the electrodes. A third optical waveguide (21) is mounted on the cantilever beam and has a third tapered end (60) disposed between the first and second tapered ends of the first and second waveguides, so that the third tapered end is in proximity with the first tapered end when the cantilever beam is in the first position and is in proximity with the second tapered end when the cantilever beam is in the second position.
