1. An apparatus comprising:
an optical waveguide including a distal end portion extending continuously along a longitudinal axis, the distal end portion having a distal end surface non-normal to the longitudinal axis, the distal end surface defining a proximal portion of an interface configured to redirect electromagnetic radiation out of the optical waveguide in a direction lateral to the longitudinal axis;
a reinforcement component having a proximal end surface disposed distal to the distal end surface of the optical waveguide, the proximal end surface defining a distal portion of the interface;
a gap disposed between the distal end surface of the optical waveguide and the proximal end surface of the reinforcement component, the gap having a non-zero width along the longitudinal axis; and
a capillary component with (i) a first interior surface coupled to an outer surface of the optical waveguide along a first length extending proximally from the distal end surface of the optical waveguide, and (ii) second interior surface coupled to an outer surface of the reinforcement component along a second length extending distally from the proximal end surface of the reinforcing component,
wherein the gap is sealed by the capillary component, and the interface includes a fluid sealed in the gap.
