We show the fabrication and the electro-optical characterization at 2.9 K of a photon number resolving detector modified to obtain a pulse position resolution. The detector exploits the spatial multiplexing of four SNSPDs connected in series: each pixel has in parallel an on-chip resistor of different value Ri. To improve the signal to noise ratio (SNR) of the pulse-position-resolving detector (PPRD), two parallel wires arranged in the so-called SNAP configuration has been used in each pixel.

Abstract
We show the fabrication and the electro-optical characterization at 2.9 K of a photon number resolving detector modified to obtain a pulse position resolution. The detector exploits the spatial multiplexing of four SNSPDs connected in series: each pixel has in parallel an on-chip resistor of different value Ri. To improve the signal to noise ratio (SNR) of the pulse-position-resolving detector (PPRD), two parallel wires arranged in the so-called SNAP configuration has been used in each pixel.File in questo prodotto:
