Innolume Introduces Commercially Available Watt-Class BOA at 1260 nm
Innolume introduces the BOA1260050YY950MXXXX, a commercially available watt-class booster optical amplifier delivering 950 mW CW fiber-coupled output power at 1260 nm. It combines a 50 nm 3-dB gain bandwidth with a compact 14-pin butterfly package and an integrated thermoelectric cooler (TEC).
Built on Innolume’s GaAs quantum-dot platform, the amplifier is designed to support reliable high-power operation.
The BOA can be combined with Innolume DFB lasers in the 1260 nm wavelength range, pairing a semiconductor seed laser with a dedicated power amplification stage. At 25 °C, the amplifier reaches 950 mW with a drive current of up to 3 A and 100 mW (20 dBm) of optical signal power delivered to its input. The seed laser must provide sufficient power to account for any optical losses before the amplifier.
Figure. Typical CW output power versus drive current at 25 °C with a 100 mW (20 dBm) input signal at 1260 nm, demonstrating output power reaching 1 W. ASE power from both fiber ports and the forward voltage, measured without an input signal, are shown for reference.
