Figure 4: Length and wavelength analysis.
(a) Average transmittance for highly correlated inputs (red circles) as a function of fibre length. Losses for single-mode coupling are of 2 dB m−1 (red circles). Average losses are of 62 dB m−1 (blue squares). (b,c) Report the transmittance maps obtained, respectively, with a 638 nm input and with a 532 nm input. (d,e) Report the intensity profile at the fibre output tip for the two wavelengths (638 and 532 nm, respectively) for the input at rstar, location indicated with a star in b,c. Scale bar, 4 μm (d,e).
