Observation of Chiral State Transfer Without Encircling an Exceptional Point

Hadiseh Nasari, Gisela Lopez-Galmiche, Helena E. Lopez-Aviles +7

The adiabatic theorem, a corollary of the Schrödinger equation, manifests itself in a profoundly different way in non-Hermitian arrangements, resulting in counterintuitive state tr…

Direct Modulation of Electrically Pumped Coupled Microring Lasers

Chi Xu, William E. Hayenga, Demetrios N. Christodoulides +2

We demonstrate how the presence of gain-loss contrast between two coupled identical resonators can be used as a new degree of freedom to enhance the modulation frequency response o…

Simultaneous Sorting of Wavelengths and Spatial Modes using Multi-Plane Light Conversion

Yuanhang Zhang, He Wen, Alireza Fardoost +5

We propose a wavelength-mode sorter realized by multi-plane light conversion (MPLC). For the first time, to our best knowledge, wavelengths and spatial modes can be sorted simultan…

Measuring the frequency response of optically pumped metal-clad nanolasers

Chi Xu, William E Hayenga, Mercedeh Khajavikhan +1

We report on our initial attempt to characterize the intrinsic frequency response of metal-clad nanolasers. The probed nanolaser is optically biased and modulated, allowing the emi…

Chiral state-conversion without encircling an exceptional point

Absar U. Hassan, Gisela L. Galmiche, Gal Harari +4

Dynamically varying system parameters along a path enclosing an exceptional point is known to lead to chiral mode conversion. But is it necessary to include this non-Hermitian dege…

Garnet-free optical circulators monolithically integrated on spatially modified III-V quantum wells

Parinaz Aleahmad, Mercedeh Khajavikhan, Demetrios Christodoulides +1

Optical circulators are indispensable components in photonic networks that are aimed to route information in a unidirectional way among their N-ports1,2. In general, these devices…
