Dynamically reconfigurable THz quantum walk comb laser through subharmonic excitation
Valerio Digiorgio, Robert Matthew Gray, Marco Raffa +5
On-chip frequency combs are increasingly relevant to both laser science and applications. Broad bandwidths and flat-top spectral envelopes are especially desirable for precision sp…
Amplitude- and frequency-modulated combs from an actively locked metasurface external-cavity laser
Marco Raffa, Jordane Bloomfield, Yu Wu +5
Optical frequency combs are key components of several photonics applications including spectroscopy, communications, and ultrafast photonics. A central challenge in frequency-comb…
Time-resolved spectroscopy of noise-driven collective states of light
Diego Piciocchi, Ina Heckelmann, Alexander Dikopoltsev +6
We study a collective liquid state of light in a fast-gain laser. Controlled temporal noise on the cavity modulation creates a fluctuating linear potential along the synthetic freq…
Ultrafast Non-Hermitian Skin Effect
Barbara Schneider, Alexander Dikopoltsev, Markus Bestler +5
Topological phases of matter commonly feature protected states at their boundaries. Transferring this protection to time-metamaterials is extremely challenging, as it requires the…
Non-Hermitian topology and skin modes in the continuum via parametric processes
Markus Bestler, Alexander Dikopoltsev, Oded Zilberberg
We demonstrate that Hermitian, nonlocal parametric pairing processes can induce non-Hermitian topology and skin modes, offering a simple alternative to complex bath engineering. Ou…
Spectral shaping of fast-gain frequency combs through phases in synthetic dimensions
Diego Piciocchi, Alexander Dikopoltsev, Ina Heckelmann +3
Optical frequency comb devices have unlocked new capabilities in telecommunications, sensing, and metrology. Yet, precise in situ control of the comb spectral envelope remains extr…
A Quantum Walk Comb Source at Telecommunication Wavelengths
Bahareh Marzban, Lucius Miller, Alexander Dikopoltsev +3
We demonstrate a quantum walk comb in synthetic frequency space formed by externally modulating a semiconductor optical amplifier operating in the telecommunication wavelength rang…
Quench dynamics of Wannier-Stark states in an active synthetic photonic lattice
Alexander Dikopoltsev, Ina Heckelmann, Mathieu Bertrand +4
Photonic emulators have facilitated the investigation of numerous solid-state phenomena and have contributed to the development of optical devices inspired by quantum mechanics. Al…
