Summary:A laser system comprising:a burst-mode laser comprising a metallic layer that serves as an electrode pad for the burst-mode laser ; andan electric heater situated atop the burst-mode laser and comprising:a first titanium layer atop the metallic layer ;a silicon dioxide layer atop the first titanium layer ;a second titanium layer atop the silicon dioxide layer ; anda platinum layer atop the second titanium layer,wherein the second titanium layer and the platinum layer serve as a heating pad for the electric heater,wherein the two titanium layers help bond SiO2 to other metals, andwherein the SiO2 layer has a thickness no more than 300 nanometers, wherein the SiO2 layer allows efficient heat transfer from the electric heater to the burst-mode laser, and wherein the SiO2 layer blocks current injection from the heating pad to the electrode pad.
