The complex sculpted gadget created by Paul Barclay and his group of physicists is so small that is can be just viewed under a microscope. But their diamond microdisk could result in great advances in telecommunications, computing and other divisions.
Barclay and his research team, which is an associate of the University of Calgary’s Institute for Quantum Technology and Science and the National Institute of Nanotechnology – have created the very first nano-sized optical resonator from a singular diamond crystal that is even a mechanical resonator.
The team also identified in the mechanical movement of the device and coupling of light; ever-lasting mechanical vibrations resulted out of the light energy trapped and bounced inside the diamond micro-disk optical cavity.
“The diamond optochemical gadgets deliver a platform to analyze the quantum functionality of microscopic objects,” says Barclay, an associate lecturer of astronomy and physics and Alberta Innovates Scholar in Quantum Nanotechnology in the Science Faculty. “Such gadgets also possess numerous potential applications, comprising color shift technology, art or work sensing feature, computing technologies, and quantum information.”
The quantum nanophotonics comprises introducing nanoscale and micro-scale circuits for analyzing light. Despite microcircuits in which electricity is released by wires present in cell phones, computers, and other telecommunication techniques – nanophotonics comprises transferring light through wires. It is similar to fiber optic technology, but at much tinier and probably more intricate scale, enabling information to be transferred more efficiently and more densely.
Nanophotonic technology also is a benefit to scientists advancing novel regimes of quantum physics, which is the nature of energy and matter on the subatomic and atomic level. “The potential to grab the light in nanoscale volumes in a visual cavity generates high electromagnetic intensity from smaller volumes of light, and augments light-matter communications that are usually close to impossible,” says Barclay.
The Ph.D. students of Barclay, comprise Behzad Khanaliloo and Matthew Mitchell, who are the head authors of the study, structured the microdisk from officially available single-crystal, synthetic diamond chips. The researchers also crafted and created the system to estimate the device’s mechanical and optical properties. The group comprises doctoral student David Lake and also a master student Tamiko Masuda as well as postdoctoral expert J.P. Hadden, who utilized facilities at the National Institute for Nanotechnology.
“By vitally discovering a novel nan0-fabrication process for single-crystal diamond, we have illustrated a gadget that is pushing the state-of-the-art in cavity optomechanics,” says Mitchell. “It also possesses the great promise for analyzing an on-chip platform to regulate the light interaction, as well as interaction of electrons and vibrations.”
According to Khanalioo, “We are excited about utilizing such gadgets for contriving methods to generate connections for quantum based computers.” He also stated that “Just creating the gadget within the community of nanophotonics research team, is a big accomplishment. I would also like to say that we are one of the finest teams in the world and thanks to the entire group of students in generating optical probes to emit light into and out of such gadgets.”
