Photonics integrated circuitry would benefit considerably from the ability to arbitrarily control waveguide cross-sections with high precision and low loss, in order provide more degrees of freedom manipulating propagating light. Here, we report a new method for femtosecond laser writing optical-fiber-compatible glass waveguides, namely spherical phase-induced multicore (SPIM-WG), which addresses this challenging task three-dimensional on-chip light control. Fabricating heating regime...
Abstract Optical Skyrmions have many important properties that make them ideal units for high-density data applications, including the ability to carry digital information through a discrete topological number and independence of spatially varying polarization other dimensions. More importantly, nature optical Skyrmion heuristically suggests strong degree robustness perturbations, which is crucial reliably carrying in noisy environments. However, study still its infancy. Here, we quantify...
This work characterizes the splitting ratio for output light in laser written directional couplers dependent on input polarization state. The theoretical analysis presented is supported by experimental results.
This work characterizes a phenomenon in direct laser written directional couplers where the splitting ratio for output light is dependent on input polarization state. In general, waveguides, different coupling strengths exist states of light. If linear state not aligned with one symmetry axes system, an additional amplitude beating imposed transfer interaction length. We present results in-plane and out plane couplers, which are supported by theoretical analysis. These new provide insights...
