研究目的
To review the fundamentals and recent advances in parity–time symmetric laser devices, discussing their unique properties and providing an outlook on this emergent field.
研究成果
The review concludes that applying concepts of PT symmetry to laser design combines two exciting fields of strong modern interest: lasers and non-Hermitian quantum mechanics. The attributes of non-Hermitian quantum mechanics provide a new way of thinking in the design of laser devices, leading to new functions such as single mode lasing in ring lasers, gain-induced lasing suppression or loss-induced lasing, lasing and anti-lasing (CPA), and vortex lasing.
研究不足
The experimental exploration of parity–time symmetry in electronics is challenging, and the review focuses on photonic realizations where flexibility exists in realizing non-Hermitian eigenstates involving optical gain and loss.
