Impact of coherent mode coupling on noise performance in elliptical aperture VCSELs for datacom
Cristina Rimoldi, Lorenzo L. Columbo, Alberto Tibaldi +4
We study the dynamical behavior of medium-size multimode VCSELs with an elliptical oxide aperture, selected for the best trade-off between high output power and modulation speed fo…
Unified theory for frequency combs in ring and Fabry-Perot quantum cascade lasers: an order-parameter equation approach
Carlo Silvestri, Massimo Brambilla, Paolo Bardella +1
We present a unified model to describe the dynamics of optical frequency combs (OFCs) in quantum cascade lasers (QCLs), incorporating both ring and Fabry-Pérot (FP) cavity configur…
Driven bright solitons on a mid-infrared laser chip
Dmitry Kazakov, Theodore P. Letsou, Marco Piccardo +13
Despite the ongoing progress in integrated optical frequency comb technology, compact sources of short bright pulses in the mid-infrared wavelength range from 3 μm to 12 μm so far…
Nozaki-Bekki optical solitons
Nikola Opačak, Dmitry Kazakov, Lorenzo L. Columbo +8
Recent years witnessed rapid progress of chip-scale integrated optical frequency comb sources. Among them, two classes are particularly significant -- semiconductor Fabry-Perót las…
Observation of electro-activated localized structures in broad area VCSELs
J. Parravicini, M. Brambilla, L. Columbo +5
We demonstrate experimentally the electro-activation of a localized optical structure in a coherently driven broad-area vertical-cavity surface-emitting laser (VCSEL) operated belo…
Reconfigurable photoinduced metamaterials in the microwave regime
Carlo Rizza, Alessandro Ciattoni, Francesco De Paulis +4
We investigate optically reconfigurable dielectric metamaterials at gigahertz frequencies. More precisely, we study the microwave response of a subwavelength grating optically impr…
