A new generation of ultra-small and high-precision lasers emerges

27.04.2012
INRS helps revolutionize the world of lasers

Ultra fast, robust, stable, and high precision: these are some of the characteristics of a new laser developed by an international research team. This ultra-small laser paves the way for a new generation of highly powerful, ultra-stable integrated lasers.

Professor Roberto Morandotti and his team at the INRS University's Énergie Matériaux Télécommunications Research Centre played a leading role in the design of this versatile laser that recently made the front page of the prestigious scientific journal Nature Communications.

"We advanced a new approach to develop a laser that boasts as yet unparalleled stability and precision, allowing us to conduct new experiments and open up new realms of research," said Professor Morandotti, who was elected a fellow by the Optical Society of America and by the International Society for Optics and Photonics (SPIE). "Plus, a multitude of applications may be created in biology, medicine, materials processing, IT, high speed communications, and metrology."

Flexible and effective, this ultra-small laser stands out for its mode of operation. The researchers developed a ring resonator (a key laser key component) that has the unique feature of playing a dual role by acting both as a filter and a non-linear element. This is the first time researchers have successfully integrated a resonator and a micro-ring in the laser component that makes it possible to better control the light source. It is manufactured using a special glass capable of harnessing the nonlinear optical properties central to laser operation.

For the first time, the researchers tested the filter-driven four-wave mixing method, which presents a number of advantages. Notably the method makes it possible to increase the laser's stability and resistance to external disruptions, increase the amplitude of light pulses while reducing their duration, and emit extremely high quality, high-repetition-rate pulses of up to 200 gigahertz or more, while maintaining a very narrow spectral bandwidth.

Working on Professor Roberto Morandotti's team at INRS, researchers Marco Peccianti and Alessia Pasquazi helped design the operating schematics of the new laser and amplifier, and helped build the prototype. Digital simulations were performed by Pasquazi.

This research benefited from the financial support of the Natural Sciences and Engineering Research Council of Canada, Fonds de recherche du Québec – Nature et technologies (FRQNT), and the Australian Research Council.

INRS

Institut national de recherche scientifique (INRS) is a graduate and postgraduate research and training university. First in Canada in terms of research intensity (grants per professor), INRS brings together some 150 professors and close to 700 students and postdoctoral fellows in its centres in Montreal, Quebec City, Laval, and Varennes. INRS research teams conduct fundamental research essential to the advancement of science in Quebec as well as internationally and play a critical role in developing concrete solutions to problems facing our society.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
