reference_without_mode_cleaning_endcap.txt			               Transmission spectra using direct free-space launch with angle offset of (a) 0◦, (b) 0.55◦, (c) 1.1◦ and transmission spectra when launching through the mode-cleaning end-cap with angle offset of (d) 0◦, (e) 0.55◦, (f) 1.1◦. The blue, red, yellow, violet, and green curves represent x-axis misalignment of 0, 2, 4, 6, and 8 µm, respectively.

Fig7_LP11_LP02_comparison.xlsx			                              Cross-coupling efficiency into LP11 and LP02 modes for various x-axis misalignments and angle misalignment of (a) 0◦ and (b) 1.1◦. LP11: without (blue dots) and with (orange asterisk) mode-cleaning end-cap. LP02: without (yellow pentagram) and with (violet triangle) mode-cleaning end-cap.
