Beschreibung
Zusammenfassung:	The invention relates to a single photon detector device (10) for detecting an optical signal (36), comprising at least one optical waveguide (12) and a nanowire (18), wherein: the at least one waveguide (12) is designed to guide the optical signal (36) along an optical axis (14) in two opposing directions (16a, 16b); the nanowire (18) is curved at least in some parts within a region (20) defined by the at least one waveguide (12); the nanowire (18) is shaped in such a way that within a region (20) defined by the at least one waveguide (12) the nanowire (18) a) is substantially mirror-symmetrical with respect to a plane (24) perpendicular to the optical axis (14), or b) is substantially point-symmetrical with respect to a point (26) within the region (20) defined by the at least one waveguide (12); within the region (20) defined by the waveguide (12) deviations of up to ± 5% in each spatial direction and/or of up to ± 10 μm along the optical axis are possible.
