BRAGG GRATING EXTERNAL CAVITY LASER

摘要

A Bragg grating external cavity laser apparatus may comprise the combination of a slider and an external cavity laser. The slider includes a waveguide that delivers light to a recording media. The external cavity laser includes an active region with a reflective back facet and a front facet that is externally coupled to the waveguide of the slider. The external cavity laser additionally includes a Bragg grating within the waveguide of the slider where the reflective back facet and the Bragg grating operate to define a single resonator within the external cavity.
