Theoretical Advancement Could Enable High-Coherence Fano Lasers

Researchers at the Technical University of Denmark (DTU) have shown that a Fano laser has fundamental advantages over other types of microscopic lasers. The researchers demonstrated that the coherence of a Fano laser can be significantly improved, compared to existing microscopic lasers, in work that supports future applications in integrated photonics, interfacing of electronics and photonics, and optical sensing. Fano interference could allow the realization of ultrafast and low-noise nanolasers (Fano lasers), optical transistors, and quantum devices working at the level of a single photon, the researchers said. The work is supported by a Villum Center of Excellence, NATEC; a newly established Danish National Research...
