Cambridge, United Kingdom / Delft, Netherlands, 22nd April 2024: Toshiba Europe Ltd. and Single Quantum B.V. have collaborated to test and validate long-distance deployments of Quantum Key Distribution (QKD) technology. Following extended validation testing of Toshiba’s QKD technology and Single Quantum’s superconducting nanowire single photon detectors (SNSPDs), both companies are pleased to announce a solution that substantially extends the transmission range for QKD deployment over fibre connections, up to and beyond 300km.

QKD uses the quantum properties of light to generate quantum secure keys that are immune to decryption by both high performance conventional and quantum computers. Toshiba’s QKD is deployed over fibre networks, either coexisting with conventional data transmissions on deployed ‘lit’ fibres, or on dedicated quantum fibres. Toshiba’s unique QKD technology can deliver quantum secure keys in a single fibre optic link at distances of up to 150km using standard integrated semiconductor devices. Achieving longer distance QKD fibre transmission is challenging due to the attenuation of the quantum signals along the fibre length, (the optical loss of the fibre link). To provide extended QKD transmission, operators typically concatenate fibre links together with trusted nodes along the fibre route which house QKD systems that relay the secret keys.

Semrock stocks the widest selection of Raman-spectroscopy edge filters available, with edge wavelengths from 224 to 1550nm. These filters are so steep and highly transmitting that they out perform even the leading holographic notch filters, yet are less than half the price. Now you can see the weakest signals closer to the laser line than before. With deep laser-line blocking, ultra-wide and low-ripple passbands, proven hard-coating reliability, and high laser damage threshld, they offer performance that lasts.

Edinburgh Instruments announces the launch of its new QYPro Integrating Sphere, designed to enhance the quantum yield capabilities of the FLS1000 Spectrometer.

The QYPro is a new integrating sphere accessory for the FLS1000 Photoluminescence Spectrometer. It fits inside the sample chamber for the best sensitivity, and it is easily adapted to different applications such as quantum yield, reflectance, electroluminescence, solid or liquid samples. The QYPro’s unique automated sample loading mechanism is not only user-friendly, but it also eliminates the possibility of sphere contamination ensuring accurate results and reducing maintenance costs.

CEO of Edinburgh Instruments Roger Fenske. “Our team of product engineers and application scientists have been working tirelessly to develop a product that delivers real results in accuracy and efficiency, and we’re confident that the QYPro will exceed our client’s expectations and are delighted to bring it to market today.”

The new black wall FluoroDish Cell Culture Dishes from WPI reduce reflections by providing a barrier for the ambient light, giving you clearer fluorescent images.

They are an excellent option for fluorescence live cell imaging by reducing the ambient light.

As with other FluoroDish in the range from WPI, the optical quality glass bottom is as thin as the coverslip to ensure the least amount of distortions, and excellent UV transmission. Each pack is individually packaged and gamma sterilised.

Coherent's new PM10K+ is a significant addition to our range of power measurement products, doubling the level of power that can be measured and now covering the full range of Coherent's high-power lasers.

These 10 kW water-cooled laser power sensors feature a 65 mm x 65 mm sensor with the BB+ coating that can handle power densities from 6 kW/cm² (at 1 kW) to 3 kW/cm² (at 10 kW). The sensor can measure up to 10 kW continuously and up to 12 kW on an intermittent basis (< 5 min). You can choose from USB + DB-25 or RS-232 communication options. The DB-25 + USB sensor models are compatible with Coherent’s stand-alone power meters, which can be ordered separately.

There will be significant developments in this product line, both new sensors and accessories during this coming year.
