Improved Far-Field Angle in Narrow-Ridge High-Power Laser Diodes Using a Double Stripe Structure

We propose a novel double stripe structure for achieving a narrow far-field angle without significant output power loss in narrow-ridge high-power broad-area laser diodes. By introducing double SiO<sub>2</sub> stripes on the top side of the laser diode, we effectively suppress high-order...
