Abstract

In this paper, we demonstrate spectrum narrowing and wavelength stabilization (both thermal and temporal) with a subwavelength resonant grating (SRG) for a single broad area laser (BAL) emitter running at moderate pump current. Our method is simple, low cost and easy to implement. A narrower spectrum width and much higher stability could be achieved on a BAL with antireflective coated front facet. Using the same approach to narrow and stabilize all the emitters on a laser diode array is under way
