Dynamical control of non-hermitian coupling between sub-threshold nanolasers enables Q-switched pulse generation
Kristian Seegert, Roberto Gajardo, Guillaume Huyet +2
Non-Hermitian photonics provides a framework to engineer the gain and loss of optical modes in open systems, enabling control of their spectral and dynamical properties. In particu…
Time-Resolved dynamics of semiconductor nanolaser via four-wave mixing gating
Federico Monti, Guilhem Madiot, Giuseppe Modica +5
We experimentally demonstrate the direct time-domain characterization of photonic-crystal nanolasers at telecom wavelengths using a nonlinear optical gating technique based on four…
Harnessing coupled nanolasers near exceptional points for directional emission
Guilhem Madiot, Quentin Chateiller, Alexandre Bazin +5
Tailoring the losses of optical systems within the frame of non-Hermitian physics has appeared very fruitful in the last few years. In particular, the description of exceptional po…
Room-temperature silicon platform for GHz-frequency nano-electro-opto-mechanical systems
D. Navarro-Urrios, M. F. Colombano, G. Arregui +7
Nano-electro-opto-mechanical systems enable the synergistic coexistence of electrical, mechanical, and optical signals on a chip to realize new functions. Most of the technology pl…
Vibrational resonance amplification in a thermo-optic optomechanical nanocavity
Guilhem Madiot, Sylvain Barbay, Rémy Braive
Vibrational resonance amplifies a weak low-frequency signal by use of an additional non-resonant high-frequency modulation. The realization of weak signal enhancement in integrated…
