Abstract:
The present disclosure generally relates to a HAMR head and a method for fabrication thereof. The HAMR head has a write head with a waveguide extending therethrough. A laser diode is coupled to a submount that is bonded to the write head using an adhesion layer, a solder structure, and a self-propagating multilayer alloying stack.
