Abstract: A waveguide comprising: a tapered-width first waveguide portion and second waveguide portions and a third waveguide portion, such that along a first direction, widths of a first and the second waveguide portions gradually increase towards a first end of the third waveguide portion, and a distance, in a second direction, between the first waveguide portion and the second waveguide portion gradually decreases from a second end of the first waveguide portion to the first end of the first waveguide portion, wherein the second direction is perpendicular to the first direction; and the maximum distance Gmax between the second end of the first waveguide portion and a second end of the second waveguide portion is greater than 0.2 μm and less than 0.48 μm; and the waveguide has a refractive index between 2 and 4 at a 1550 nm wavelength.

Abstract: A waveguide array that includes a plurality of waveguides disposed in a substrate. The plurality of waveguides include one or more first waveguides that have a first propagation constant and one or more second waveguides that have a second propagation constant, where the first propagation constant differs from the second propagation constant. The one or more first waveguides and the one or more second waveguides are disposed in the substrate in a linear distribution and at least a portion of the linear distribution is arranged based on a quasi-periodic sequence having a plurality of sequence segments. Each sequence segment is determined based on a quasi-periodic function, has an order, and corresponds to an arrangement segment of a first waveguide, a second waveguide, or combinations thereof. The linear distribution includes at least one arrangement segment corresponding with a third-order sequence segment or higher of the quasi-periodic sequence.

Abstract: A binary photonics lattice that includes a waveguide array having a plurality of single mode waveguides disposed in a substrate, the plurality of single mode waveguides including one or more first waveguides having a first V-number V1 and one or more second waveguides having a second V-number V2. The first V-number V1 is smaller than the second V-number V2. The one or more first and second waveguides are arranged in a linear distribution having first and second edge waveguide regions and a binary waveguide region positioned between the first and second edge waveguide regions. The binary waveguide region is a symmetrical binary representation of a decimal number of two or greater. Further, the binary waveguide region includes at least one first waveguide representing a digit 0 of the symmetrical binary representation and/or at least one second waveguide representing a digit 1 of the symmetrical binary representation.

Abstract: A multicore optical fiber that includes a plurality of waveguiding cores disposed in a cladding. The plurality of waveguiding cores include one or more first waveguiding cores that have a first propagation constant and one or more second waveguiding cores that have a second propagation constant, where the first propagation constant differs from the second propagation constant. The one or more first waveguiding cores and the one or more second waveguiding cores are disposed in the cladding in a ring distribution and at least a portion of the ring distribution is arranged based on a quasi-periodic sequence having a plurality of sequence segments. Each sequence segment is determined based on a quasi-periodic function, has an order, and corresponds to an arrangement segment of a first waveguiding cores, a second waveguiding cores, or combinations thereof. The ring distribution includes at least one arrangement segment corresponding with a third-order sequence segment or higher of the quasi-periodic sequence.

Abstract: A multicore optical fiber that includes a plurality of waveguiding cores disposed in a cladding. The plurality of cores are situated adjacent to at least one other core with a core center to core center spacing being not larger than 10 times the radius of the average core, such that the greater than 10% of the light will couple from one core to the adjacent core over a propagating distance of 1 cm, along the fiber length so as to provide coupling between the adjacent cores and to enable quantum walk. The plurality waveguiding cores are disposed in the cladding in a ring distribution or at least a portion of the ring distribution.
