Jonathan Scott said:As far as I know, there is no known mechanism by which gravitational waves could give rise to electromagnetic waves in empty space.
What would happen if that space is not exactly empty? BHs sometimes have accretion disks. Inspiraling BH pair may have an accretion disk which encompass both BHs at once. The inner portion of the disk is quite hot, it's a plasma. Plasmas exhibit various complex EM properties.
