White papers

05 June 2020

One of the most promising candidates for the perfect quantum qubit are defect centres in solid-state materials, also known as colour centres, which have been found to emit a single photon per excitation event when excited by laser light of a particular frequency. An important technique for characterizing these colour centers is photoluminescence excitation (PLE) spectroscopy, which measures the tiny optical signals produced by single-photon emitters when they are excited by continuous-wave (cw) laser light. Widely tunable cw lasers based on OPO technology make it quicker and easier to characterize the internal energy structure of different qubit contenders. This white paper presents such a suitable tunable cw laser source, outlining the advantages and illustrating examples of how this laser can be used to characterize novel colour centers.

Controlling the quality and yield of crops will be crucial elements of increased food production. Growing crops in greenhouses and vertical farms (greenhouse factories) will allow us to better control the process of growing food and, in the case of vertical farms, move food production closer to the consumer (vertical farms can be integrated into existing structures such as warehouses). In greenhouses, LEDs are a popular lighting option to provide the spectral energy to crops for photosynthesis and other growth processes.

This whitepaper will explore how optical sensing is used for real-time monitoring of LED greenhouse lighting, and how this can be used to manage colour and power output.
