1. A glass waveguide assembly, comprising:

  • a glass substrate comprising a body with a front-end section having a front end, a back-end section having a back end, a top surface extending parallel to an X-Y plane of the glass substrate, a bottom surface extending parallel to an X-Y plane of the glass substrate;

    a waveguide array comprising a plurality of glass optical waveguides formed within a glass matrix of the body of the glass substrate, the glass optical waveguides running from the front-end section to the back-end section of the glass substrate and comprising respective optical end faces at the back end section of the glass substrate;

    slots cut out of the back end of the glass substrate from the top surface of the glass substrate to the bottom surface of the glass substrate along an X-Z plane of the glass substrate to create waveguide sections in respective connector regions of the glass waveguide assembly, the slots separating the connector regions of the glass waveguide assembly along a direction X in the X-Z plane of the glass substrate;

    a multi-fiber optical connector formed at or adjacent the back end of the glass substrate in each of the connector regions, each multi-fiber optical connector terminating the plurality of glass optical waveguides of the waveguide array at the respective optical end faces of the glass optical waveguides at the back end section of the glass substrate to provide optical communication to the plurality of glass optical waveguides formed within the glass matrix of the body of the glass substrate.
