Key Performance Metrics: Responsivity, Bandwidteh, and Noise
For any photodetector upon in optikal recever, three metrics dominate decectory (A / W), bandwiddddecth (Hz), and noise equilizer power (NEP).
| Parameter | Typical Graphene Detector | Conventional (InGaAs/Ge) |
|---|---|---|
| Responsivity (A/W) | 0.001 – 1 (without gain) | 0.5 – 1.0 |
| Bandwidth (3dB) | 50 – 200 GHz | 10 – 60 GHz |
| Dark Current | Low (μA scale) | Low to moderate |
| Spectral Range | UV to THz | Typically 900-1700 nm |
| Temperature Range | Broad (cryogenic to 400K) | Limited by material |
