Assemblies, optical connectors, and methods for forming fiber arrays using laser bonded optical fibers are disclosed. In one embodiment, a method of forming a fiber array includes placing an optical fiber on a surface of a substrate, directing a laser beam into the optical fiber disposed on the surface of the substrate, melting, using the laser beam, a material of the substrate to create a first laser bond zone between the optical fiber and the surface of the substrate, applying an adhesive to the optical fiber and the substrate to create an adhesive bond zone between the optical fiber and the surface of the substrate, and cutting the optical fiber and the substrate to create a first section of the fiber array and a second section of the fiber array. The first section of the fiber array includes a first portion of the optical fiber, a first portion of the substrate, a first portion of the adhesive bond zone, and the first laser bond zone, and the second section of the fiber array includes a second portion of the optical fiber, a second portion of the substrate, and a second portion of the adhesive bond zone.
