Abstract
Watt-class semiconductor optical amplifiers (SOAs) at 1550 nm are an attractive alternative to replace erbium-doped fiber amplifiers (EDFAs) in various applications including remote sensing, optical communications, and LIDAR, with the potential to be more efficient, compact, and cost-effective. We report a world record of a single mode fiber-coupled packaged semiconductor optical amplifier delivering >30 dBm (1.2 W) of continuous wave ex-fiber power at 1550 nm, enabled by recent advancements in diffraction-limited output from tapered diode laser amplifiers. This result is achieved with an input seed power of 30 mW (~15 dBm), corresponding to an overall gain of ~16 dB, and the noise figure is calculated to be 5.4 dB. We have begun reliability testing of our tapered laser chips, and we are investing in the productization of these packaged watt-class SOAs.
