(Color online) Schematic diagram of the experimental setup.
(Color online) (a) Reflectance (R) and transmittance (T) of laser measured as a function of applied voltage. The absorption (A), A = 1 − (R + T), of the excitation laser is shown as a function of applied bias (b) and injection current (c).
(Color online) Ratio of current spill-over as a function of injection current.
(Color online) (a) External quantum efficiencies as a function of the current density of two LEDs that show distinct efficiency droop behavior and (b) measured current spill-over of the samples.
