When two lattices with distinct angles or periodicities come together, they conjure a moiré superlattice—a realm where astonishing phenomena like superconductivity and optical solitons spring to life. At the heart of this ...
The formation of dissipative solitons is influenced by several factors, such as spectral filtering effects and Kerr nonlinear effects. This interaction leads to the possibility of mode locking over a wide range of parameters, ...
Microcombs can help us discover planets outside our solar system and track new diseases in our bodies. But current microcombs are inefficient and unable to reach their full potential. Now, researchers at Chalmers University ...
Non-Hermitian systems with their spectral degeneracies known as exceptional points (EPs) have been explored for lasing, controlling light transport, and enhancing a sensor's response.
On January 15, 2022, the Hunga Tonga-Hunga Ha'apai volcano in Tonga exploded, releasing large amounts of energy into the atmosphere and ocean, causing tsunamis across the Pacific Ocean. Scientists from the Shocks, Solitons ...
Researchers have shown that dissipative Kerr solitons (DKSs) can be used to create chip-based optical frequency combs with enough output power for use in optical atomic clocks and other practical applications. The advance ...
New theoretical and experimental physics research shows the first ever creation of a diverse range of fine-sized, special polarization structures known as solitons in a multiferroic material. While solitons have been previously ...
Streams of ultrashort light pulses delivered from mode-locked laser resonators stimulate potential applications in ultrafast science and information technology. Here the elementary pulse entity, termed dissipative solitons ...
The transition to chaos is ubiquitous in nonlinear systems. Continuous-wave-driven photonic-chip-based Kerr microresonators exhibit spatiotemporal chaos, also known as chaotic modulation instability.
Passive mode-locked technology utilizes saturable absorbers' nonlinear absorption effect to regulate the cavity's loss and phase to generate mode-locked pulses. Graphene has a unique energy bandgap structure, a low absorption ...
