Efficient low-power terahertz generation via on-chip triply-resonant nonlinear frequency mixing

چکیده
In this letter, we show theoretically how the light-confining properties of triply-resonant photonic resonators can be tailored to enable dramatic enhancements of the conversion efficiency of terahertz THz generation via nonlinear frequency down-conversion processes. Using detailed numerical calculations, we predict that this approach can be used to reduce up to three orders of magnitude the pump powers required to reach quantum-limited conversion efficiency of THz generation in conventional nonlinear optical material systems. Furthermore, we propose a realistic design readily accessible experimentally, both for fabrication and demonstration of optimal THz conversion efficiency at sub-W power levels. © 2010 American Institute of Physics. doi:10.1063/1.3359429

Design of an efficient terahertz source using triply resonant nonlinear photonic crystal cavities.
We propose a scheme for efficient cavity-enhanced nonlinear THz generation via difference-frequency generation (DFG) processes using a triply resonant system based on photonic crystal cavities. We show that high nonlinear overlap can be achieved by coupling a THz cavity to a doubly-resonant, dual-polarization near-infrared (e.g. telecom band) photonic-crystal nanobeam cavity, allowing the mixin...
متن کاملUpper limits on terahertz difference frequency generation power in quantum well heterostructures
There is currently considerable interest in terahertz (THz) difference frequency generation (DFG) utilizing near-resonant intersubband nonlinearity in quantum cascade lasers and other quantum well heterostructures. Such devices were shown to operate at room temperature, but their power demonstrated so far has been rather low. In all previous works the intracavity configuration was studied, in w...

متن کاملDifference-frequency generation with quantum-limited efficiency in triply-resonant nonlinear cavities.
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 ...

Enhanced THz generation is achieved by employing a nonlinear optical disk resonator with a high value of second-ord...
