Aerosol doped Nd planar silica waveguide laser

Aerosol doped neodymium planar silica waveguide lasers on silicon are reported for the first time. The waveguide lasers were fabricated by a combination of flame hydrolysis deposition (FHD) and reactive ion etching (RIE). A threshold of 22 mW and a slope efficiency of 2.5% were achieved. >
