To support the miniaturization of optical devices and components, a scientific team led by researchers at ITMO University has devised a quick, affordable method to make visible-light nanophotonic chips. The light source for the chip can be grown directly on a waveguide in a Petri dish using solution chemistry methods — a much less expensive approach than nanolithography.
Today’s optical chips operate in the infrared (IR) range. “But to make the devices even more compact, we need to work in the visible range, as the size of a chip depends on the wavelength of its emission,” researcher Sergey Makarov said.
The modern photonics industry is constantly working on making its devices more compact, be it…READ MORE
