With a total of 5 patents to his name, Liu's work has advanced the understanding and application of laser systems.
Latest Patents
One of Jiaren Liu's latest patents focuses on the "Stable linewidth narrowing of a coherent comb laser." This innovative technique aims to narrow the linewidth of multiple lines of a coherent comb laser (CCL) concurrently. The process involves providing a mode-locked semiconductor CCL that outputs at least four mode-locked lines. A fraction of the power is tapped from the CCL to form a tapped beam, which is then propagated to an attenuator to produce an attenuated beam. This attenuated beam is reinserted into the laser cavity, ensuring that its power is less than 10% of the tapped beam. This reinsertion allows the CCL to operate with mode-locked lines, each having a linewidth of less than 80% of the original linewidth. By utilizing a solid waveguide and maintaining polarization in the secondary cavity, improved stability of the linewidth narrowing is achieved.
Career Highlights
Jiaren Liu is currently employed at the National Research Council of Canada, where he continues to push the boundaries of laser technology. His work has not only contributed to academic knowledge but has also had practical implications in various industries.
