Refractive index profile (thin solid line) and shape of the fundamental mode (thick dash-dot line). The inset shows the vertical far field pattern of the fundamental mode .
Dependence of lasing wavelength and threshold current density (top) and reciprocal differential quantum efficiency (bottom) on cavity length for the PBC lasers.
Light-current characteristic of a broad area PBC laser in pulsed mode. The inset shows the vertical far field patterns at different drive currents.
Light-current (solid line), voltage-current (dashed line), and wall-plug efficiency-current (dash-dot line) dependence for a single mode PBC laser in cw mode. The inset shows the lateral far field patterns at various drive currents.
