Optical parametric generation in periodically poled lithium niobate

Abstract

We present recent experimental and simulation results for broad-band, off-axis infrared light generation by a parametric down-conversion process. We use a periodically poled lithium niobate in the experiments. Our simulations explore the competition between on-axis and off-axis signal generation. We explore the contrast between a narrow pump and a broad pump on the emission spectrum.

Broadband and off-axis optical parametric generation in periodically poled LiNbO_3

Yiyi Guan, Joseph W. Haus, Peter Powers

A model is presented that includes broadband, off-axis light generation for parametric downconversion processes. We apply this to parametric generation with material parameters adapted for periodically poled lithium niobate; our simulations are compared with experimental results. Our simulations explore the competition between on-axis and off-axis signal generation. With a broad-area pump, we find that a shorter crystal is more effective at suppressing off-axis signal generation.

Broadband optical parametric amplification at the communication band with periodically poled lithium niobate

Oc‐Yeub Jeon, Min-Ji Jin, Hwan Hong Lim +2 more

We report broadband optical parametric generation (OPG) in a single periodically poled lithium niobate crystal with a picosecond pump pulse at a fixed wavelength. We also demonstrate efficient optical parametric amplification of a broadband seed pulse within the quasi-phase-matched OPG band. The broad parametric gain band is attributed to group-velocity matching and degeneracy between the signal and idler, and the broad spectral width of the pumping source.

Macroscopie quantum fluctuations of pulsed nanosecond optical parametric generation in periodically-poled LiNbO3

Yiyi Guan, Joseph W. Haus, Peter Powers

We present simulations and experimental results for quantum noise initiated emission from a periodically- poled lithium niobate optical parametric generator (OPG). Our model successfully describes broad-band emission spectra in OPGs and optical parametric amplifiers. The emission spectra and the quantum statistics deduced from macroscopic fluctuations between simulations and experiment are compared.

Macroscopic quantum fluctuations of pulsed nanosecond optical parametric generation in periodically-poled LiNbO3

Yiyi Guan, Joseph W. Haus, Peter Powers

We present simulations and experimental results for quantum-noise-initiated emission from an optical parametric generator (OPG) fabricated from periodically poled lithium niobate. The model we employ, which includes transverse coupling effects to enable off-axis phase matching, has been successfully used for describing broadband emission spectra in OPG's and optical parametric amplifiers. The emission spectra and the quantum statistics deduced from macroscopic fluctuations are compared between simulations and experiment.

Simultaneous generation of two pairs of entangled photons in periodically poled lithium niobate crystals

We propose that two pairs of entangled photons will be generated simultaneously through spontaneous parametric down-conversion pumped by a monochromatic light only in periodically poled lithium niobate crystals without more complex crystal structures.
