Abstract:
Methods, systems, and apparatus, including a laser including a layer having first and second regions, the first region including a void; a mirror section provided on the layer, the mirror section including a waveguide core, at least part of the waveguide core is provided over at least a portion of the void; a first grating provided on the waveguide core; a first cladding layer provided between the layer and the waveguide core and supported by the second region of the layer; a second cladding layer provided on the waveguide core; and a heat source configured to change a temperature of at least one of the waveguide core and the grating, where an optical mode propagating in the waveguide core of the mirror section does not incur substantial loss due to interaction with portions of the mirror section above and below the waveguide core.

Claim (Index 6):
A semiconductor laser, comprising:\n a substrate; a layer formed on the substrate, the layer having first and second regions, the first region of the layer including one or more voids; a gain section provided on the layer, the gain section comprising:\n a first waveguide core; \n a p-type region and an n-type region that form a p-n junction; and \n a contact layer configured to apply a voltage to forward bias the p-n junction of the gain section; \n a first mirror section provided on the layer, the first mirror section comprising:\n a second waveguide core, wherein at least part of the second waveguide core is provided over a first void; \n a first grating; and \n a first heat source configured to change a temperature of the second waveguide core or the first grating; \n a phase section provided on the layer, the phase section comprising:\n a third waveguide core; and \n a second heat source configured to change a temperature of the third waveguide core; \n a second mirror section, the second mirror section comprising:\n a fourth waveguide core, wherein at least part of the fourth waveguide core is provided over a second void; \n a second grating; and \n a third heat source configured to change a temperature of the fourth waveguide core or the second grating; and \n wherein the first waveguide core, the second waveguide core, the third waveguide core, and the fourth waveguide cores are configured to optically communicate with one another, and wherein an optical mode propagating in the first mirror section or the second mirror section does not incur substantial loss due to interaction with portions of the first mirror section outside the second waveguide core or portions of the second mirror section outside the fourth waveguide core.
