Innolume Extends Watt-Class Quantum-Dot BOA Lineup to 1130 nm

Innolume introduces the BOA1130040YY950MXXXX, a watt-class booster optical amplifier delivering 950 mW CW fiber-coupled output power at 1130 nm. It combines a 40 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. Its quantum-dot gain medium provides an alternative to highly strained InGaAs/GaAs quantum-well designs in this wavelength region.

Beyond conventional amplifier applications, the 1130-1140 nm region is of interest for atomic spectroscopy, including research involving thulium near 1140 nm. Higher infrared power provides additional power budget for optical experiments and potential frequency-conversion applications, such as generating visible light through frequency doubling.

The new model complements Innolume’s high-power BOAs at 1260 nm and 1310 nm, extending the portfolio to shorter wavelengths.

The BOA can be combined with a suitable Innolume seed laser. At 25 °C, the device reaches 950 mW with a drive current of approximately 2.2 A and 100 mW (20 dBm) of optical signal power delivered to its input. Seed-laser selection must account for any optical losses before the amplifier.

The module is available with PM980 or HI1060 fiber, with a 900 µm loose tube as an option.
