A blue superluminescent LED (SLED) with power above 100mW was fabricated. These SLED shows promise for focus-free pico-projection due to reduced interference and improved image quality. We compared different straight and curved waveguide designs with and without tilted facets. Internal and mirror losses were determined by the Hakki-Paoli method.
