SPD_OEM_NIR – Single Photon Detector from AUREA Technology
The SPD_OEM_NIR is a compact, self-contained single-photon detector engineered for Quantum Key Distribution (QKD), long-range LiDAR, and time-resolved photonics across the 900 nm to 1,700 nm spectral band. Housed in a 2U rack-compatible enclosure, it provides high-sensitivity photon counting and robust noise suppression for both OEM integration and laboratory research without cryogenic cooling.
Detection is powered by a thermoelectrically cooled InGaAs/InP Geiger-mode SPAD supporting both asynchronous free-running and synchronous gated modes, with external gating up to 100 MHz. Active temperature stabilization and fast quenching enable precise arrival timestamping with timing jitter down to 150 ps at 30% QE.
At 1,550 nm, calibrated quantum efficiency (QE) from 10% to 30% pairs with a dark count rate below 700 cps (at 10% QE, 20 µs dead time) and an afterpulsing probability under 0.1%. In high-speed quantum channels, this ultra-low afterpulsing suppresses accidental coincidence counts, directly minimizing Quantum Bit Error Rate (QBER) at clock rates up to 100 MHz.
Designed for streamlined integration, the unit features a dedicated UART port for FPGA/microcontroller control alongside USB connectivity and full Python, C, C++, and LabVIEW APIs. This delivers a reliable, plug-and-play solution tailored for various applications including quantum networking, trace gas sensing, TCSPC, and photon source characterization.
TPS_1550_TYPE_S – Entangled Photon Source from AUREA Technology
The TPS_1550_TYPE_S is a next-generation, room-temperature entangled photon source engineered for Quantum Internet networks, Quantum Key Distribution (QKD), and quantum communications across the telecom C and L bands. Housed in a compact 19" 1U rack enclosure, it generates stable, high-visibility entangled photon pairs in both polarization and energy-time domains without cryogenic cooling.
Photon pairs are generated via Spontaneous Parametric Down-Conversion (SPDC) in a Periodically Poled Lithium Niobate (PPLN) waveguide using quasi-phase matching and an ultra-stable CW pump laser. Precise thermal management maintains phase matching over extended runtimes, while optical filtering strips residual pump light and background fluorescence.
This optical architecture delivers exceptional state purity, achieving a Coincidence-to-Accidental Ratio (CAR) of 2,000 typical with accidental noise suppressed to just 0.10% of total signal data. Emitting across a broad spectral bandwidth centered at 1550 nm, the source achieves a polarization visibility of 99% typical, ensuring seamless interoperability with standard telecom DWDM infrastructure.
Built-in remote management provides direct command over operational parameters via an embedded UART interface, USB connectivity, GUI software, and DLLs. The TPS_1550_TYPE_S delivers an essential, high-purity building block for quantum repeaters, Bell-state analysers, and multi-node quantum networks.

Deep UV Laser Diodes of Ultec distributed by EQ Photonics
Ultec is pioneering a new frontier of ultra-wide band gap semiconductors. Following gallium nitride (GaN)—the breakthrough material behind innovations like blue LEDs and transistors for compact AC adapters—aluminum nitride (AlN), an ultra-wide band gap semiconductor, is emerging as the next-generation material capturing global attention. At the forefront of ultra-wide band gap semiconductor innovation, Ultec specialize in AlN-based device technologies, a field where Ultec has developed strong expertise. AlN offers exceptional potential for deep ultraviolet optoelectronics and next-generation power devices. Leveraging Ultec’s expertise in AlN, they are developing groundbreaking devices that will shape the future of technology. Ultec devices currently lasing wavelengths from 265 nm to 295 nm, with development underway to extend the range up to 325 nm. 
Silanna UV distributed by EQ Photonics
The Australian company Silanna manufactures UV LEDs with short wavelengths such as 233 nm, 235 nm, 237 nm and 255 nm. The LEDs are available in SMD housings with flat windows and lenses, as well as in TO housings with lenses. The main applications for these LEDs are disinfection and sensor technology, e.g. gas measurement. For disinfection, far UVC (235 nm) is safer for skin and eyes than deep UVC (255 nm to 280 nm). These UV LEDs are now available for sale from EQ Photonics GmbH. The LEDs are supplied in tape & reel, gel box, tray or on star board. We look forward to your inquiry!Hydrogen fluoride detection with 2476 nm DFB laser diodes
Hydrogen fluoride (HF) is a very poisonous gas. Therefore, it is very important to detect it in small traces. The laser manufacturer Norcada from Canada, represented in Europe by EQ Photonics, introduced a DFB laser diode with emission wavelength 1278 nm which is optimized for HF detection. The laser diode is assembled in a TO39 package with TEC and thermistor. The typical optical power is 10 mW. A variant with collimation lens is available as well. Here you get a beam diameter below 4 mm in distance of 2 meters. Further available for HF detection stay the 2476 nm DFB laser diodes without or with lens.
