Coherent perfect absorption (CPA), or anti-lasing, has been so far inherently restricted to continuous wave scenarios, drastically restricting its applications to standard linear steady-state systems. However, future technologies based on enhanced light-ma ...

Mode-locking and Q-switching are two widely used pulsing techniques based on different mechanisms. In practice, both lasing regimes can be realized within the same laser system, while the current research on their transition dynamics presents challenges in ...

The continuous growth of global data traffic over the past three decades, along with advances in disaggregated computing architectures, presents significant challenges for optical transceivers in communication networks and high-performance computing system ...

Epsilon-near-zero (ENZ) materials, i.e., materials with a vanishing real part of the permittivity, have become an increasingly desirable platform for exploring linear and nonlinear optical phenomena in nanophotonic and on-chip environments. ENZ materials i ...

Laser-induced forward transfer (LIFT) is a digital additive manufacturing technique that uses a pulsed laser to transfer various materials from a donor film to a receiver substrate placed in close proximity. In this work, we investigate the transfer of SU- ...

Coherent collective oscillations of electrons excited in metallic nanostructures (localized surface plasmons) can confine incident light to atomic scales and enable strong light-matter interactions, which depend nonlinearly on the local field. Direct sampl ...
