Spot size converter (SSC) in a HAMR magnetic recording head assembly have a plurality of split assist core structures. Each split assist core structure includes multiple assist cores and a main waveguide. Each split core may also include one or more side waveguides such that the main waveguide is sandwiched between the side waveguides and top and bottom assist cores. Adjacent split assist core structures, may share assist cores. The split assist core structures reduce light source power utilized to write data to magnetic media.
