Abstract:
A hybrid external cavity laser and a method for configuring the laser having a stabilized wavelength is disclosed. The laser comprises a semiconductor gain section and a volume Bragg grating, wherein a laser emission from the semiconductor gain section is based on a combination of a reflectivity of a front facet of the semiconductor gain section and a reflectivity of the volume Bragg grating and the reflectivity of the semiconductor gain section and the volume Brag grating are insufficient by themselves to support the laser emission. The hybrid cavity laser further comprises an etalon that provides further wavelength stability.

Claim (Index 15):
A device configured to generate at least one laser emission, the device comprising:\n a semiconductor gain section configured to generate a light emission, said semiconductor gain section comprising: a gain region having a known length;\n a rear facet having a first reflectivity; and \n a front facet having a second reflectivity, said gain region, \n rear facet and front facet forming a first resonant cavity having a first plurality of resonances; and a volume Bragg grating, having a known reflectivity configured to:\n receive said light emission, and \n reflect a portion of the received light emission back into the semiconductor gain section, wherein said volume Bragg grating and the rear facet of the semiconductor gain section form a second resonant cavity overlapping the first resonant cavity, said second resonant cavity generating a second plurality of resonances, wherein neither the first resonant cavity nor the second resonant cavity exhibit sufficient modal gain for either the first plurality of resonances or the second plurality of resonances to individually achieve a lasing threshold and wherein said at least one laser emission occurring at substantially coincident ones of said first plurality of resonances and said second plurality of resonances.
