Complex Edge-State Phase Transitions in 1D Topological Laser Arrays
Midya Parto, Steffen Wittek, Hossein Hodaei +7
We report the first observation of lasing in topological edge states in a 1D Su-Schrieffer-Heeger active array of resonators. We show that in the presence of chiral-time ($\mathcal…
Ultrasensitive micro-scale parity-time-symmetric ring laser gyroscope
Jinhan Ren, Hossein Hodaei, Gal Harari +5
We propose a new scheme for ultra-sensitive laser gyroscopes that utilizes the physics of exceptional points. By exploiting the properties of such non-Hermitian degeneracies, we sh…
Measurement of the second-order coherence function for metallic nanolasers
William E. Hayenga, Hipolito Garcia-Gracia, Hossein Hodaei +4
Due to the high spontaneous emission coupled into the resonance mode in metallic nanolasers, there has been a debate concerning the coherence properties of this family of light sou…
Integrable nonlinear parity-time symmetric optical oscillator
Absar U. Hassan, Hossein Hodaei, Mohammad-Ali Miri +2
The nonlinear dynamics of a balanced parity-time symmetric optical microring arrangement are analytically investigated. By considering gain and loss saturation effects, the pertine…
Metallic Coaxial Nanolasers
William E. Hayenga, Hipolito Garcia-Gracia, Hossein Hodaei +2
The last two decades have witnessed tremendous advancements in the area of nanophotonics and plasmonics. Undoubtedly, the introduction of metallic structures has opened a path towa…
Single mode lasing in transversely multi-moded PT-symmetric microring resonators
Hoseein Hodaei, Mohammad-Ali Miri, Absar U. Hassan +4
Single mode lasing is experimentally demonstrated in a transversely multi-moded InP-based semiconductor microring arrangement. In this system, mode discrimination is attained by ju…
Nonlinear reversal of PT symmetric phase transition in a system of coupled semiconductor micro-ring resonators
Absar U. Hassan, Hossein Hodaei, Mohammad-Ali Miri +2
A system of two coupled semiconductor-based resonators is studied when lasing around an exceptional point. We show that the presence of nonlinear saturation effects can have import…
Parity-time-symmetric coupled microring lasers operating around an exceptional point
Hossein Hodaei, M. Ali Miri, Absar Ul Hassan +4
The behavior of a parity-time (PT) symmetric coupled microring system is studied when operating in the vicinity of an exceptional point. Using the abrupt phase transition around th…
PT-symmetric microring lasers: Self-adapting broadband mode-selective resonators
Hossein Hodaei, Mohammad-Ali Miri, Matthias Heinrich +2
We demonstrate experimentally that stable single longitudinal mode operation can be readily achieved in PT-symmetric arrangements of coupled microring resonators. Whereas any activ…
