Product information "SPAD Single-Photon InGaAs/InP Avalanche Photodiodes APD"

1100-1600 nm; Responsivity 0.8 A/W; Capacitance 0.25 pF; Dark Current 0.1 nA; Package 3-pin TO 46, 6-pin TO-8, 10-pin Mini-Flat

Wooriro’s SPAD series (Single Photon Avalanche Diode) comprises InGaAs/InP APD devices specially designed and fabricated for the use of single photon avalanche detection (SPAD) with internal or external cooling systems.

SPAD avalanche photodiodes (APDs) can be operated at the voltage above breakdown for short periods, this mode of operation is called “Geiger mode” or “Gated mode” operation. Ultra-low noise operation is possible at a case temperature of -40 °C. The devices can be used for quantum key distribution (QKD) receivers.

SPAD devices are available without an integrated thermoelectric cooling device (TEC) in a 3-pin TO-46 package or with integrated TEC in a 6-pin TO-8 package as well as in a butterfly-style 10-pin Mini-Flat package.
