Defined in this way, K is proportional to the inverse square of a device’s noise equivalent power, NEP = (hv/QE) × (2D)1/2. For our parameters a K of 20,000 corresponds to an NEP ∼5 × 10-18 W/Hz1/2. The reader should bear in mind that this is a gated detection setup, with the signal power confined to time windows that are open for a fraction of time of order 10-3.
