| Zusammenfassung | We present the design and construction of a Predictable Quantum Efficient Detector (PQED), suggested to be capable of measuring optical power with an uncertainty of 1 ppm. The detector is based on custom-made inversion layer photodiodes operated at low temperatures using a reverse bias mode. Encouraging quantum efficiency results are obtained from three-dimensional modelling of a cylindrically symmetric photodiode. A constructed test PQED was compared with a silicon trap detector at the temperatures of 77 K, 173 K and 300 K with varied reverse biases from 0 V to 8 V. Our preliminary results show that the quantum efficiency at 488 nm is 1 within the measurement uncertainty of 500 ppm. |
