Output power spectrum of an InGaAs photodiode emitter.
GaAs and InGaAs Photomixers
Emitter/receiver modules for TeraBeam
- GaAs and InGaAs-based emitter/receiver modules
- Fully packaged modules with SM/PM fiber pigtail
- Up to 100 µW output power
- New: Rh:InGaAs receivers, more than 10 dB signal improvement with TeraScan 1550
- Requires TeraBeam 780 or TeraBeam 1550
Having teamed up with some of the leading terahertz research institutes, TOPTICA is able to provide top-quality GaAs and InGaAs photomixers. Both material systems offer an excellent bandwidth and dynamic range. The modules come equipped with a Silicon lens and SM/PM fiber pigtail. The all-fiber design eliminates the need for time-consuming laser beam alignment, and enables an easy and flexible integration into any terahertz assembly.
