2. Devices are sensitive to electrostatic discharge (ESD). Appropriate precautions should be taken by user.


The 1500 to 1600 nm auraTM semiconductor optical amplifier (SOA) is the world’s first c-band diffraction-limited watt-class amplifier. This product is intended to replace bulky, inefficient, and expensive erbium-doped fiber amplifiers (EDFAs). The chip architecture is based on a single-mode tapered waveguide amplifier which can be easily coupled into from a single mode fiber (SMF). The nearly diffraction-limited output enables efficient coupling to single-mode fiber and maximizes far-field irradiance when collimated in free space. Various packaging configurations are offered including: 1) hard-soldered junction-down on C-mount, 2) hard-soldered junction-down on ceramic submount, and 3) unsoldered bare chip.

The auraTM product line is intended to address applications such as free space optical communication, sensing, and LIDAR in consumer, industrial, and defense markets by enabling watt-level direct use output from a semiconductor chip source.
