Coherent LQG Control, Free-Carrier Oscillations, Optical Ising Machines and Pulsed OPO Dynamics
Ryan Hamerly
Broadly speaking, this thesis is about nonlinear optics, quantum mechanics, and computing. More specifically, it covers four main topics: Coherent LQG Control, Free-Carrier Oscilla…
Reduced models and design principles for half-harmonic generation in synchronously-pumped optical parametric oscillators
Ryan Hamerly, Alireza Marandi, Marc Jankowski +3
We develop reduced models that describe half-harmonic generation in a synchronously-pumped optical parametric oscillator above threshold, where nonlinearity, dispersion, and group-…
Topological defect formation in 1D and 2D spin chains realized by network of optical parametric oscillators
Ryan Hamerly, Kensuke Inaba, Takahiro Inagaki +3
A network of optical parametric oscillators is used to simulate classical Ising and XY spin chains. The collective nonlinear dynamics of this network, driven by quantum noise rathe…
A 16-bit Coherent Ising Machine for One-Dimensional Ring and Cubic Graph Problems
Kenta Takata, Alireza Marandi, Ryan Hamerly +6
Many tasks in our modern life, such as planning an efficient travel, image processing and optimizing integrated circuit design, are modeled as complex combinatorial optimization pr…
Comprehensive analysis of the optical Kerr coefficient of graphene
Daniel B. S. Soh, Ryan Hamerly, Hideo Mabuchi
We present a comprehensive analysis of the the nonlinear optical Kerr effect in graphene. We directly solve the S-matrix element to calculate the absorption rate, utilizing the Vol…
Large-scale Ising spin network based on degenerate optical parametric oscillators
Takahiro Inagaki, Kensuke Inaba, Ryan Hamerly +3
Simulating a network of Ising spins with physical systems is now emerging as a promising approach for solving mathematically intractable problems. Here we report a large-scale netw…
