We present an InGaAs/InP single-photon avalanche diode (SPAD) with 10 mu{m}-diameter active area, designed for fiber-based quantum applications. Improved design and fabrication lead to low dark count rate (1000 cps at 225 K), 25% photon detection efficiency and 100 ps (FWHM) timing jitter.

Abstract

We present an InGaAs/InP single-photon avalanche diode (SPAD) with 10 mu{m}-diameter active area, designed for fiber-based quantum applications. Improved design and fabrication lead to low dark count rate (1000 cps at 225 K), 25% photon detection efficiency and 100 ps (FWHM) timing jitter.
