1. A laser-cleaved optical fiber apparatus comprising:
at least one optical fiber housed within a ferrule, wherein the ferrule has a ferrule end face, wherein the at least one optical fiber has a fiber end face including an end face core, each fiber end face of the optical fibers having a surface area, the surface area comprising a rough area that defines at least a portion of the surface area, wherein the rough area does not include the end-face core;
wherein the rough area has a surface roughness between 0.1 μm and 0.5 μm root mean squared (rms) as measured by a confocal microscope; and
wherein the end face of the at least one optical fiber is spaced from the ferrule end face at a distance between 1 micron and 50 microns.
