Abstract

We develop a theoretical framework for second-order nonlinear difference frequency generation in triply resonant wavelength-scale cavities, demonstrating stable CW conversion with quantum-limited efficiency. We propose a scheme for efficient THz generation based on this framework.

Difference-frequency generation with quantum-limited efficiency in triply-resonant nonlinear cavities

Ian B. Burgess, Alejandro W. Rodríguez, Murray W. McCutcheon +4 more

We present a comprehensive study of second-order nonlinear difference frequency generation in triply resonant cavities using a theoretical framework based on coupled-mode theory. We show that optimal "quantum-limited" conversion efficiency can be achieved at any pump power when the powers at the pump and idler frequencies satisfy a critical relationship. We demonstrate the existence of a broad parameter range in which all triply-resonant DFG processes exhibit monostable conversion. We also demonstrate the existence of a geometry-dependent bistable region.

Degenerate four-wave mixing in triply resonant Kerr cavities

David M. Ramirez, Alejandro W. Rodríguez, Hila Hashemi +3 more

We demonstrate theoretical conditions for highly efficient degenerate four-wave mixing in triply resonant nonlinear (Kerr) cavities. We employ a general and accurate temporal coupled-mode analysis in which the interaction of light in arbitrary microcavities is expressed in terms of a set of coupling coefficients that we rigorously derive from the full Maxwell equations. Using the coupled-mode theory, we show that light consisting of an input signal of frequency ${\ensuremath{\omega}}_{0}\ensuremath{-}\ensuremath{\Delta}\ensuremath{\omega}$ can, in the presence of pump light at ${\ensuremath{\omega}}_{0}$, be converted with quantum-limited efficiency into an output shifted signal of frequency ${\ensuremath{\omega}}_{0}+\ensuremath{\Delta}\ensuremath{\omega}$, and we derive expressions for the critical input powers at which this occurs. We find the critical powers in the order of 10 mW, assuming very conservative cavity parameters (modal volumes $~10$ cubic wavelengths and quality factors $~1000$). The standard Manley-Rowe efficiency limits are obtained from the solution of the classical coupled-mode equations, although we also derive them from simple photon-counting ``quantum'' arguments. Finally, using a linear stability analysis, we demonstrate that maximal conversion efficiency can be retained even in the presence of self- and cross-phase modulation effects that generally act to disrupt the resonance condition.

Nonlinear harmonic generation and devices in doubly resonant Kerr cavities

Hila Hashemi, Alejandro W. Rodríguez, John D. Joannopoulos +2 more

We describe a theoretical analysis of the nonlinear dynamics of third-harmonic generation $(\ensuremath{\omega}\ensuremath{\rightarrow}3\ensuremath{\omega})$ via Kerr $({\ensuremath{\chi}}^{(3)})$ nonlinearities in a resonant cavity with resonances at both $\ensuremath{\omega}$ and $3\ensuremath{\omega}$. Such a doubly resonant cavity greatly reduces the required power for efficient harmonic generation, by a factor of $\ensuremath{\sim}V∕{Q}^{2}$, where $V$ is the modal volume and $Q$ is the lifetime, and can even exhibit 100% harmonic conversion efficiency at a critical input power. However, we show that it also exhibits a rich variety of nonlinear dynamics, such as multistable solutions and long-period limit cycles. We describe how to compensate for self- and cross-phase modulation (which otherwise shifts the cavity frequencies out of resonance), and how to excite the different stable solutions (and especially the high-efficiency solutions) by specially modulated input pulses.

On-chip ultra-broad frequency conversion via simultaneous second and third-order optical nonlinearity

Steven A. Miller, Kevin J. Luke, Yoshitomo Okawachi +3 more

We demonstrate ultra-broad frequency conversion through simultaneous second and third-order nonlinearities. Using a high-Q resonator, we generate multiple frequency lines in both the near-IR and in the visible range using a single near-IR CW pump.

High-efficiency cascaded up and down conversion in nonlinear Kerr cavities

Chao Zhou, Peter A. Bermel

In this work, we derive general conditions to achieve high efficiency cascaded third harmonic generation and three photon parametric down conversion in Kerr nonlinear resonant cavities. We employ the general yet rapid temporal coupled-mode method, previously shown to accurately predict electromagnetic conversion processes in the time domain. In our study, we find that high-efficiency cascaded third harmonic generation can be achieved in a triply resonant cavity. In contrast, high-efficiency cascaded three-photon parametric down conversion cannot be achieved directly in a triply resonant cavity, although a combination of two doubly resonant cavities and three waveguides is an effective alternative. The stabilities of the calculated steady-state solutions for both processes are revealed by applying Jacobian matrices. Finally, we find that the inclusion of self- and cross- phase modulation introduces multi-stable solutions. Further study is required to find a simple way to reliably achieve stable conversion at the highest possible efficiency.
