Abstract

The slab coupled optical waveguide laser (SCOWL) is a promising candidate for high power, single mode emitter for a number of reasons, including its near diffraction limited optical quality, large modal size and near circular output pattern. Current SCOWL designs have limited electrical-optical power conversion efficiency (PCE) around 40%, which is lower than conventional RWG laser and broad area laser that are known to have much higher PCEs. To improve the SCOWL PCE, we theoretically optimize its structure by reducing Al content, increasing doping concentration and introducing a GRIN layer to prevent carrier leakage. Numerical simulations predict that an optimized SCOWL design has a maximum PCE of about 57% at room temperature.

Fig. 1

The cross-section of the simulated SCOWL device. Only half of the structure is included in the simulation because of the symmetrical plane on the left boundary. A perfect match layer (PML) is placed on the right boundary of the simulation window to damp high order leaky modes.

(a) Simulated I–V characteristics for SCOWL design 1. The blue dotted line corresponds to the simulated data points, and the red line shows the linear fitting at 1A to obtain the series resistance and turn-on voltage. Ith stands for the threshold current. The areas of the rectangles correspond to the power distribution (see details in the context). The length of the laser is 3mm. The width of the rib is 4.5μm for all the designs in this study. The reflectivity is 32% on both facets. (b) The calculated L-I curve and PCE.

Band diagram under certain bias voltage for the SCOWL design 2 with and without GRIN layer. The red lines are the conduction band (CB) and the blue line is the quasi-Fermi level. The inset illustrates a triangular potential barrier that electrons encounters when traveling through the p-waveguide layer.
