High-performance microring resonator developed by INRS researchers

10.02.2010
New step toward ultra-fast optical communications

A new, more efficient low-cost microring resonator for high speed telecommunications systems has been developed and tested by Professor Roberto Morandotti's INRS team in collaboration with Canadian, American, and Australian researchers.

This technological advance capitalizes on the benefits of optical fibers to transmit large quantities of data at ultra-fast speeds. The results of the team's work, just published in the prestigious journal Nature Photonics, will facilitate the transition from electronic to optical communications, the future solution for meeting the growing needs of Internet and cellphone users.

The microring resonator investigated by Professor Morandotti's team at INRS's Energy, Materials, and Telecommunications Center in Varennes, Quebec, and by his colleagues, offers several advantages. Made from a special glass with exceptional optical properties, this key signal transmission component can be incorporated into the microchips used extensively in telecommunications systems. Furthermore, it is fabricated using the same methods as those employed by silicon chip manufacturers, thereby reducing optical component costs and making the technology more affordable.

The new resonator has the additional advantage of using a single low-power laser source to obtain multiple wavelengths, unlike existing devices that require very high optical power, or different devices. Furthermore, Professor Morandotti and his team have been successful in generating a new multiple-wavelength laser source at a threshold optical power level as low as ~54mW, setting a new world record for glass devices in the process.

This technological breakthrough is crucial because it comes as electronic devices are reaching their data transmission capacity limit, whereas optical fibers offer much greater capacity and better transmission quality. In addition to revolutionizing the world of telecommunications, INRS researchers are helping create new applications in the fields of detection and metrology, including measurement applications in physics and computers, as well as instrument calibration and adjustment.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
