INRS Supports Development of Advanced High-Precision and Ultra-Small Lasers

INRS University's Énergie Matériaux Télécommunications Research Centre’s team of researchers led by Professor Roberto Morandotti designed and developed a new laser.

This high precision, ultra fast, stable and versatile laser was highlighted in the front page of the scientific journal Nature Communications.

The newly developed ultra-small laser has a unique operation mode, in addition to being efficient and flexible. Furthermore, a key laser key component known as the ring resonator with exceptional capability of functioning both as a filter and a non-linear element was developed by the researchers. For the first time, this rare integration of resonator with micro-ring within the laser component has been achieved by researchers, which will enable controlling the light source. It is created based on a special glass that can bind the non-linear optical properties to the focal point of laser operation.

The researchers validated the filter-driven four-wave mixing method that incorporates multiple benefits. This method will enhance the laser's consistency and also ensure protection against external disruptions. In addition, the amplitude of light pulses will be enhanced with relatively short duration. A narrow spectral bandwidth will be maintained and high-repetition-rate pulses of over 200 GHz of high-efficiency will be generated.

Along with the INRS team directed by Professor Roberto Morandotti, two scientists Alessia Pasquazi and Marco Peccianti enabled to execute the operation methodology of the new laser and amplifier, thereby constructing the prototype. However, Pasquazi successfully conducted digital simulations.
