Sample A2, propagation loss measurement by cutback. Distance is given in units of mm. Signal is given separately for 3 waveguide widths (nominally 4.9, 5.3, and 5.7um) and 5 waveguides of each width. 4p9 stand for 4.9um and so on. Signal is in units of mV. Base signal with no chip between objective lenses was 6945.0mV. Loss calculation was done by first averaging data for each combination of waveguide length and width. Subsequently, data out of 1-sigma range were disregarded. The remaining data were averaged again, converted in logarithmic decay, and the propagation loss was obtained by a linear fit of the deca data. The constant offset has the meaning of a sum of in-coupling and out-coupling loss.
