University of Waterloo’s Institute researchers have developed a new quantum sensor that detects light. These sensors are the first-of-its-kind, built on semiconductor nanowires which can detect even a single light particle’s efficiency and speed. With advanced technology, the invention of such sensors promise to improve remote sensing capabilities and quantum communication.
However, the primary intention behind developing such quantum sensors is to widen application areas. The principle of efficient light detection helps in broadening quantum sensors’ applications in surveillance, quantum radar, and nighttime operation. Previously during surveillance or nighttime operation, few light particles used to return to the devices which hampered the performance. However, the new quantum sensor helps in reducing such hurdles.
Quantum Sensor Extends Telecommunication Bandwidth for Better Performance
The next generation quantum sensor ensures detection of every single particle of light- photon that comes in. Moreover, these sensors are so efficient and fast that apart from detecting, they can also absorb photons. However, researchers have further created a range of tapered nanowires, following the formula of absorbing light particles using quantum sensors. These nanowires have the capability of converting incoming photons into electric current.
The invention of such quantum sensors hopes to outperform various technologies along with bringing rapid advancements in 3-D imaging. The single photon detection mechanism of quantum sensors also helps in detecting singlet oxygen for monitoring drug dose in cancer treatment. Such medical solution in treating cancer is a milestone in the field of oncology.
Due to quality materials, doping profile, and proper shape and arrangement, semiconducting nanowire achieves timing resolution and high speed. Therefore, the sensors built on this semiconductor nanowires can detect a broad spectrum of light with high timing resolution. Now, researchers are emphasizing on broadening the spectrum absorption range for quantum sensors using different materials.
