Uploaded Archive (RAR) includes 5 data files that are Excel format (.xlsx)

The figures are as follows:

Fig. 1: The back-reflection and coupling loss of spliced SMF-HCF connection.

Fig. 4. The relationship between coupling loss and offset of light propagated through GRINs with different cleave angles to a NANF.

Fig. 7. Simulated and measured back-reflection from angle-cleaved GRINs with SMF-GRIN offset. Simulations: offset (given next to the data points) optimized for minimum coupling loss. Exper-iment: offset of 4 µm (blue stars) and 5 µm (green triangles).

Fig. 8. Back-reflection from zero-offset angle-cleaved SMF-GRIN: simulations (red line), data from literature (blue [22] and green [24] squares), and achieved experimentally here (red circles).

Fig. 11. Measured OTDR trace showing back-reflection in the offset-spliced SMF-GRIN angle-spliced to the HCF
