SPAD Single-Photon InGaAs/InP Avalanche Photodiodes APD

1250-1650 nm; Responsivity 25 A/W; Breakdown Voltage 40-70 V; Dark Current 1 nA; Package 3-pin TO 46 Wooriro’s APD module for OTDR applications is based on an InGaAs/InP avalanche photodiode (APD) in TO-46 package. This module’s APD is pigtailed, and the module can be ordered either without connector or with a SC, LC or FC type optical connector in UPC or APC version. Designed for an optical wavelength range of 1250 nm to 1650 nm, the APD module for OTDR features a very low dark current of 1 nA typical at 98% breakdown voltage. Typical responsivity is 25 A/W at 1550 nm wavelength and 10 nW optical input power. Key Features: InGaAs/InP Avalanche Photodiode APD Low Dark Current: 1 nA (Typical, @0.98 x Breakdown Voltage) High Reliability Optical Wavelength Range: 1250 nm to 1650 nm Responsivity: 25 A/W Typ.

810-1560 nm; Wavelength Accuracy ±2 nm; Pair-generation Rate 1x105-4x106 Pairs/s; Coincidence-to-accidental Ratio 100-1000; Two-photon Interference Visibility 95%-99% OZ Optics’ Ruby and Emerald systems are crystal-based polarization entangled photon sources which integrate the crystals responsible for spontaneous parametric down-conversion into photon pairs inside a self-balanced interferometer engine to generate the wavelength/polarization entanglement in a robust benchtop turn-key device. Each source comes equipped with a wavelength-stabilized pump laser, a variable optical attenuator, and a temperature controller to fine tune phase matching parameters to realize optimal efficiency. The components are packaged inside a rugged aluminium housing with an on/off power switch and keyed laser control. Signal and Idler photons are available with the pump wavelength removed at separate output ports on the front panel. Ruby entangled photon sources make use of type-0 down-conversion to generate a broadband biphoton spectrum, with a bandwidth of several tens of nanometers. Emerald entangled photon sources make use of type-2 down-conversion to generate a narrow bandwidth biphoton spectrum, with a bandwidth of a few nanometers. In both cases the interferometer engine ensures photon entanglement regardless of the down-conversion type. AMS Technologies can assist in selecting the preferred version (Ruby or Emerald) depending on your target wavelength and application – contact the AMS Technologies photonics experts to discuss your requirements.
