Hi, As far as I know MPB will solve the dispersion curves and the group velocities when given a propagation direction (k-point) and a structure, assuming the latter is periodical. So, you'll may end up simulating a lattice of several segmented waveguides but if they are separated enough there shouldn't be any problem.
Also the units don't matter that much since you'll have to specify only the segmentation related to the length of the unit cell (the duty cycle) since the program uses a normalized unit system. Maybe if you specify more about what you are trying to simulate I could help more.
