1. A waveguide assembly with an integrated active layer comprising:
a waveguide disposed on a read-layer stack;
an active layer consisting of an N-doped layer disposed proximal and integrated into a waveguide; and
a near field transducer coupled to the waveguide, wherein the near field transducer is configured to generate and support a distribution of localized surface plasmons.
