Hello,
could you please clarify what is the function of a “Waveguide Y Branch” in INTERCONNECT when used to combine 2 optical signals? Isn’t it supposed to add the vectors of the two inputs (0.5 coupling coefficient, 0 phase shift)? For example, if I have 3 optical power meters P1=-3.01189 dBm,angle= -0.13911855 rad, P2=-9.84342183dBm, angle=2.535180104 rad and at the output of the branch I observe P3=-10,0685867, angle=0.1928904821 which is not the sum of P1+P2.
