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 1):
A device configured to generate at least one laser emission, the device comprising:\n a semiconductor gain section generating a light emission, said semiconductor gain section comprising: a rear facet having a first reflectivity; and a front facet having a second reflectivity, said rear facet and said front facet forming a first resonant cavity having a first plurality of non-lasing resonance, 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 the rear facet of the semiconductor gain section and the volume Bragg grating form a second resonant cavity, overlapping the first resonant cavity, said second resonant cavity generating a second plurality of non-lasing resonances, wherein at least one of said first plurality of non-lasing resonances and a corresponding at least one of said second plurality of non-lasing is substantially coincident, said substantially at least one coincident resonance having a modal gain sufficient to generate corresponding ones of said at least one laser emission.
