(a) Schematic of the device structure: light shading denotes quantum wells and shunt; dark shading denotes barriers and a possible cladding layer. (b) The characteristic and (c) gain profile for the SL of structure 1, not including the shunt.
Snapshots of field (solid line) and electron density (dashed line) configuration at (left column) and electron density vs and (right column) for structure 1 [(a) and b)], structure 2 [(c) and (d)], and structure 3 [(e) and (f)].
Parameters used for the shunted SL.
