Integrated Planar Waveguide Amplifier With 15 dB Net Gain at 1550 nm

An integratable planar Er-doped aluminosilicate waveguide amplifier with flat gain spectrum between 1540 and 1560nm was fabricated on Silicon Optical Bench. A single pass net gain of 15dB(22dB) was measured at 1550nm (1532nm) when pumped with 150mW at 980nm in a packaged device. In a 10Gb/s BER experiment receiver sensitivities from -34.8dB to -36dB were measured in the 1532-1565nm signal band. No error floor was found.
