Abstract :
We report GaAs-based transverse-junction-superluminescent-diodes, characterized as transverse-carrier-flow spread in quantum wells horizontally instead of vertical well-by-well injection. These devices overcome the problem of non-uniform-carrier-distribution and operate at a bio-optical window of 1.1-mum wavelength regime.
