hmmm... how are laser diodes normally fibre coupled? Some are direct coupled like in the coherent CCP diode packages , 19 fibres for 19 emitters . Some are coupled with the use of a lens - mostly with single diodes , which is the case for a few 2W diodes I had that had FAC and then a lens after to focused it into the fibre
Butt coupling is the simplest method of laser diode fiber coupling, but also the least efficient because no effort is made to match the fiber’s numerical aperture. Because the laser light emitted from the active area of the diode is highly divergent, the majority of the light falls outside of the cores acceptance angle and ends up in the cladding.

Laser Diode to Fiber Coupling Surya Bikram Bhandari Nov 8, 2021 The edge emitting diodes have emission pattern full width at half maximum (FWHM) at 30 – 50 o in the plane perpendicular to active – area junction and an FWHM of 5 – 10 o in plane parallel to junction.
The focused spot of the laser diode was then coupled into an optical fiber. This coupling is critical in all three axes, X, Y, and Z. Figure 2 shows the fiber output when the diode is coupled properly in the X and Y direction, but not in Z. In this case the focus is behind the surface of the fiber, so much of the beam energy is being coupled ...
