Amplified Feedback and Spontaneous Emission Injection in Quantum Cascade Ring Laser Systems
Radhika R. Bhuckory, Sara Kacmoli, Deborah L. Sivco +1
Ring lasers exhibit rich operational regimes such as unidirectional, bidirectional, or bistable operation. The two-mode dynamics of the counter-propagating modes - clockwise (CW) a…
Hole-Based Stealthy Hyperuniform Semiconductor Metamaterials for the Mid-Infrared
Manuel Gallego, Sara Kacmoli, Yezhezi Zhang +2
Stealthy hyperuniform heterostructures are a novel type of metamaterial with the potential for optical image processing at angles away from normal incidence. These metamaterials sh…
Efficient computation of coherent multimode instabilities in lasers using a spectral approach
Sara Kacmoli, Saeed A. Khan, Claire F. Gmachl +1
Coherent multimode instabilities are responsible for several phenomena of recent interest in semiconductor lasers, such as the generation of frequency combs and ultrashort pulses.…
Photonic molecule based on coupled ring quantum cascade lasers
Sara Kacmoli, Deborah L. Sivco, Claire F. Gmachl
Photonic molecules - particular systems composed of coupled optical resonators - emulate the behavior of complex physical systems exhibiting discrete energy levels. In this work, w…
