For Quantum Technologies to fulfil their potential requires orders of magnitude reduction in size, weight, power-consumption and cost (SWaP-C) compared to many of the current generation of laboratory demonstrators. In addition, the instrument must be reliable in real-world environments where it will be exposed to vibrations, shocks and temperature changes during operation. Our REMOTE technology meets these exceptional challenges by moving beyond the established norms of laboratory based scientific lasers resulting in a miniaturised package that offers maximised stability and reliability in applications both in the lab and within robust portable instruments. REMOTE PLATFORM & DESIGN REMOTE platform is a compact narrow linewidth, micro-External Cavity Diode Laser (μ-ECDL), only 30 x 12.7 x 8.9 mm3, optimised for quantum technology applications. For example, our REMOTE-780 is optimised for Rb transitions around 780.24 nm. The laser module is designed and fabricated using Alter Technology UK’s > 17 years of experience in advanced packaging techniques that employ high reliability telecoms manufacturing and space qualified processes. The flexibility of the REMOTE platform μ-ECDL approach enables the single-frequency operation to be achieved with Fabry-Perot laser diodes whilst also offering prospects for wide tunability over the full gain spectrum and enabling the design to target a range of wavelengths specific to quantum cooling, re-pumping or other transitions. REMOTE APPLICATIONS Quantum atomic laser cooling, trapping and repumping Quantum clocks, time and frequency standards Quantum gravimeters, gradiometers, metrology, inertial navigation… Quantum computing, communications, QKD Bose-Einstein condensation Polarization-sensitive and interferometric applications Quantum applications such as optical clocks offer the promise of orders of magnitude improvement in temporal accuracy over the existing time standard. Precision timing is required for a wide range of applications including telecommunications, financial trading, navigation systems and security. However, optical clocks and other quantum technologies remain complex laboratory-bound systems.
