Abstract: A photonic system is provided. The photonic system comprises a first photonic component and a second photonic component. The photonic system additionally comprises a photonic ribbon cable comprising a waveguide extending from a first end of the photonic ribbon cable to a second end of the photonic ribbon cable and having a winding geometry configured to deform, enabling the first end of the photonic ribbon cable to be extended away from the second end of the photonic ribbon cable. The first end of the photonic ribbon cable is optically coupled to the first photonic component and the second end of the waveguide is optically coupled to the second photonic component.

Abstract: A cantilever that includes a first dielectric layer with a first intrinsic stress, a second dielectric layer overlaying the first dielectric layer, in which the second dielectric layer has a second intrinsic stress that is different than the first intrinsic stress, the cantilever including a first piezoelectric segment disposed between the first dielectric layer and the second dielectric layer at a first position with respect to a first dimension parallel to the first dielectric layer, the cantilever including a second piezoelectric segment disposed between the first dielectric layer and the second dielectric layer at a second position with respect to the first dimension, and the cantilever including one or more waveguides patterned in the second dielectric layer.

Abstract: A cantilever may include a first dielectric layer that has a first intrinsic stress and a second dielectric layer overlying the first dielectric layer that has a second intrinsic stress that is different than the first intrinsic stress. The difference between the first and second intrinsic stresses may cause the cantilever to curve. A second dielectric layer can comprise a plurality of crossbars oriented at an angle relative to a length of the cantilever to reduce curvature in a width direction of the cantilever. The second dielectric layer can be patterned with a waveguide. The cantilever may be piezoelectrically actuated.

Abstract: A method for controlling a qubit encoded in an atom-like defect in a solid-state host may comprise applying an electrical signal to a piezoelectric cantilever that is mechanically coupled to a photonic waveguide comprising one or more embedded point defect sites. The photonic waveguide may be optically coupled to a photonic chip. Applying the electrical signal to the piezoelectric cantilever may induce movement in the piezoelectric cantilever, which may induce a strain in the photonic waveguide. The applied electrical signal may be determined by a defect site with excitation light, measuring a frequency of a photon emitted by the excited defect site, determining a frequency shift based on the measured frequency of the emitted photon, and determining the electrical signal to be applied to the piezoelectric cantilever based on the frequency shift.
