Integrated SiGe Detectors for Si Photonic Sensor Platforms

Integrated SiGe Detectors for Si Photonic Sensor Platforms

In this work, we present the results of integrated Ge detectors grown on a Si photonic platform for sensing applications. The detectors are fabricated on a passive photonic circuit for maximum coupling efficiency. Measurement results at 1300 nm wavelength show a responsivity of 0.2 A/W and very low...

For a voltage range between 0 and −10 V, the dark current is better than 0.1 nA which is crucial for highly sensitivity devices and applications, like Optical Coherence Tomography.https://www.mdpi.com/2504-3900/1/4/559Si photonicsSiGe detectorsoptical coherence tomography
