    Abstract: The next-generation of optoelectronic systems will require efficient optical signal transfer between many discrete photonic components integrated onto a single substrate. While modern assembly processes can easily integrate thousands of electrical components onto a single board, photonic assembly is far more challenging due to the wavelength-scale alignment tolerances required. Here we address this problem by introducing a self-aligning photonic coupler insensitive to x, y, z displacement and angular misalignment. The self-aligning coupler provides a translationally invariant evanescent interaction between waveguides by intersecting them at an angle, which enables a lateral and angular alignment tolerance fundamentally larger than non-evanescent approaches such as edge coupling. This technology can function as a universal photonic connector interfacing photonic integrated circuits and microchiplets across different platforms. For example, it can be used in a self-aligning photonic circuit board that can be assembled more easily, with larger misalignment tolerances, than other complex optoelectronic systems.

    Abstract: Provided herein are inorganic nucleic acid supramolecular structures and methods for making them. In certain aspects, the construct includes a structured nucleic acid polymer micelle, which micelle includes a structured nucleic acid template; one or more functional moieties attached to the template; and polymers that interact with nucleic acid present in the template to form the structured nucleic acid polymer micelle; and an inorganic shell surrounding the structured nucleic acid template, in which the one or more functional moieties extend outside the structured nucleic acid polymer micelle and the inorganic shell to maintain functionality.
