What does the 'solution at an angle' in the 'data set' node of the model builder window in wave optics module of comsol 4.4 means?

I am trying to understand the exact meaning of the phrase 'solution at an angle' under 'data sets>solution' node in the model builder of comsol 4.4. the help on the topic shows following message
Enter a value for the Solution at angle (phase) (SI unit: deg). The default is 0 degrees and evaluates complex-valued expressions by multiplying the solution in the solution data set by a factor of exp(i*pi*phase/180) prior to expression evaluation.
I am not able to understand what does it exactly means. Suppose I plot the x-, y- and z- components of the fundamental mode of SI fiber then would any phase, if provided , multiply all the components equally by a factor exp(i*pi*phase/180) ?
My other question is as follows
The fundamental mode of the fiber has two polarizations, say X and Y. Suppose E1 is the electric field of the X mode and E2 is that of Y mode. Now I want to calculate the surface integral of 'E1.E2' on the fiber cross section. How is it possible in comsol 4.4.
Any help provided on the topics above will be appreciated.
Thanks a lot!
