Integrated planar waveguide amplifier with 15 dB net gain at 1550 nm

A packaged Er-doped aluminosilicate planar optical waveguide amplifier (POWA) has shown net gain of 15 dB (22 dB) at 1550 nm (1532 nm) with 150 mW/980 nm pump. Low loss (0.25 dB) mode converters that couple between the POWA and standard P-glass waveguides are also demonstrated.
