Nonlinear periodic orbit solutions and their bifurcation structure at the origin of soliton hopping in coupled microresonators
Savyaraj Deshmukh, Aleksandr Tusnin, Alexey Tikan +2
Microresonator frequency combs, essential for future integrated optical systems, rely on dissipative Kerr solitons generated in a single microresonator to achieve coherent frequenc…
Voltage-tunable OPO with an alternating dispersion dimer integrated on chip
Dmitry Pidgayko, Aleksandr Tusnin, Johann Riemensberger +3
Optical parametric oscillators enable the conversion of pump light to new frequency bands using nonlinear optical processes. Recent advances in integrated nonlinear photonics have…
Free-electron interaction with nonlinear optical states in microresonators
Yujia Yang, Jan-Wilke Henke, Arslan S. Raja +10
The short de Broglie wavelength and strong interaction empower free electrons to probe scattering and excitations in materials and resolve the structure of biomolecules. Recent adv…
Quiet point engineering for low-noise microwave generation with soliton microcombs
Andrea C. Triscari, Aleksandr Tusnin, Alexey Tikan +1
Low-noise microwave signals can be efficiently generated with microresonator-based dissipative Kerr solitons ('microcombs'). However, the achieved phase noise in integrated microco…

Miles H. Anderson, Alexey Tikan, Aleksandr Tusnin +3
We theoretically and experimentally investigate the formation of dissipative coherent structures in Kerr nonlinear optical microresonators, whose integrated dispersion exceeds the…
Chaotic micro-comb based parallel ranging
Anton Lukashchuk, Johann Riemensberger, Aleksandr Tusnin +2
The transition to chaos is ubiquitous in nonlinear systems ranging from fluid dynamics and superconducting circuits to biological organisms. Optical systems driven out of equilibri…
Dissipative structures in topological lattices of nonlinear optical resonators
Aleksandr Tusnin, Alexey Tikan, Kenichi Komagata +1
We theoretically study the dynamics and spatio-temporal pattern formation of driven lattices of nonlinear optical microresonators and analyze the formation of dissipative structure…
Dissipative Kerr solitons in a photonic dimer on both sides of exceptional point
Kenichi Komagata, Alexey Tikan, Aleksandr Tusnin +4
Exceptional points are a ubiquitous concept widely present in driven-dissipative coupled systems described by a non-Hermitian Hamiltonian. It is characterized by the degeneracy of…
Protected generation of dissipative Kerr solitons in supermodes of coupled optical microresonators
Alexey Tikan, Aleksandr Tusnin, Johann Riemensberger +6
The driven-dissipative photonic dimer comprised of two evanescently coupled high-Q microresonators is a fundamental element of multimode soliton lattices. It has demonstrated a var…
Nonlinear states and dynamics in a synthetic frequency dimension
Aleksandr K. Tusnin, Alexey M. Tikan, Tobias J. Kippenberg
Recent advances in the study of synthetic dimensions revealed a possibility to employ the frequency space as an additional degree of freedom which allows for investigating and expl…
