Coupled waveguides are convenient at implementing useful optical transformations. In this letter, we investigate the uncertainty of transformation by two coupled waveguides that stems from the perturbations of waveguide's mode indices~--- the effect that may be imposed by a non-ideal fabrication process, in particular, those of femtosecond direct laser writing. In our analysis, the perturbations are assumed to be samples of a stationary random process, characterized by an intensity and a…

Discrete optics in femtosecond-laser-written photonic structures

Over the last few years arrays of evanescently coupled waveguides have been brought into focus as a particular representation of functionalized optical materials, in which the dispersion and

Laser-written polarizing directional coupler with reduced interaction length.

An approach based on stress-induced anisotropy is demonstrated, allowing us to decrease the size of polarizing directional couplers down to 3.7 mm, almost an order of magnitude shorter than previously reported.

Anderson localization and nonlinearity in one-dimensional disordered photonic lattices.

An intermediate regime is found in which the ballistic and localized components coexist while diffusive dynamics is absent and evidence is found for a faster transition into localization under nonlinear conditions.

Discrete Spatial Optical Solitons in Waveguide Arrays

We report the observation of discrete spatial optical solitons in an array of 41 waveguides. Lightwas coupled to the central waveguide. At low power, the propagating field spreads as it couples tomore

Complete power concentration into a single waveguide in large-scale waveguide array lenses

This work uses state-of-the-art numerical methods to demonstrate complete power transfer into a single waveguide for waveguide array lenses with large numbers of waveguides and demonstrates for the first time a physical design for an ideal wave guide array lens.

Sub-thermal to super-thermal light statistics from a disordered lattice via deterministic control of excitation symmetry

Monochromatic coherent light traversing a disordered photonic medium evolves into a random field whose statistics are dictated by the disorder level. Here we demonstrate experimentally that light

Fabrication of coupled mode photonic devices in glass by nonlinear femtosecond laser materials processing.

Using the direct output of an extended cavity femtosecond laser, without the need for a laser amplifier, single mode waveguides can be rapidly fabricated with well controlled parameters.

Observation of a Topological Transition in the Bulk of a Non-Hermitian System.

The first experimental observation of a topological transition in a non-Hermitian system is presented, and standard methods for examining topological properties, which involve probing edge (or surface) states, are ignored.

Coupled-mode analysis of phase-locked injection laser arrays

For long-distance high-bit-rate optical communications it is desirable to have sources which operate in a stable single longitudinal mode and deliver maximum optical power to the receiver. One

Broadband silicon photonic directional coupler using asymmetric-waveguide based phase control.

Broadband directional couplers with various power splitting ratios, including 10%/90%, 20%/80%, 30%/70%, 40%/60% and 50%/50%, were realized for both transverse electric (TE) and transverse magnetic (TM) modes.
