1. An off-axis, fiber-array collimator, the collimator comprising:
a monolithic fiber block including a plurality of optical fibers, wherein the monolithic fiber block comprises a substrate having a first surface configured to include tips of the plurality of optical fibers in a first position configuration; and
a reflector optically coupled to the monolithic fiber block, the reflector comprising a monolithic reflector block including a plurality of thin-film parabolic reflectors, wherein positions of centers of the plurality of parabolic thin-film reflectors match the first position configuration,
wherein:
the reflector is coupled to the monolithic fiber block via a transparent adhesive layer, and
a reflector axis of the reflector is at an angle with respect to a beam axis of a beam of the plurality of optical fibers, and an axis of each of the parabolic thin-film reflectors is at the angle with respect to a beam axis of a respective beam of the plurality of optical fibers.
