A planar waveguide laser configuration for single mode operation around the 1550 nm region using multimode-diode pumping was presented. The flexibility of tailoring the asymmetry of planar waveguides was advantageously utilized in coupling light from broad area pump sources with simple optics. The device was fabricated by Ag film ion exchange in a hybrid phosphate glass having Er-doped and passive regions monolithically integrated in a single substrate. A single transverse mode waveguide output power of 54 mW was obtained.
