The Particle Swarm optization Lumerical developed is for one FOM. When you have two results to be optiized, it is doable, provided that you design a FOM to contain both of them in one value. For example if you want mimize 1-T1/T2, where T1 is the transmission for wavelewngth 1 and T2 is the transmission for wavelength 2.

 

You can design other FOM to better realize your optimization goal, as one value of FOM.
