Abstract

We report broadband optical parametric amplification in a periodically poled LiNbO3 crystal. A 20 dB-gain was obtained for a broadband signal at 1580 nm with a 35 ps-pump at a fixed wavelength of 870 nm.

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.

Broadband optical parametric amplification using PPLN waveguide pumped by detuned second harmonic

Masaki Asobe, Daiki Yagi, Yuki Kawabata +4 more

Optical parametric amplification in the range of 1.3–1.8 µm was demonstrated by using a periodically poled LiNbO3 (PPLN) waveguide as a nonlinear medium by varying the detuning of the pump wavelength. A wide range of detuning was enabled by using a multiple-quasi-phase-matched (M-QPM) LiNbO3 waveguide for pump generation through second harmonic generation (SHG) and temperature control of the PPLN waveguide. Broadband optical amplification and wavelength conversion through difference frequency generation (DFG) are considered useful for widening the bandwidth of optical communication.

Optical parametric amplification is expected as a key technique for high-speed optical fiber communication and optical quantum computing.We developed a high-gain and broadband optical parametric amplifier (OPA) module by using a periodically poled lithium niobate (PPLN) waveguide, the single-mode core of which is directly bonded to a lithium tantalate substrate.The OPA is assembled as a pump-combiner-integrated module with four optical-fiber input/output ports.By improving the fabrication processes of the PPLN waveguide and the assembly techniques of OPA modules, we achieved over-30-dB phase sensitive amplification with a continuous-wave pump.By using the PPLN waveguide, we successfully obtained over-6-dB squeezed light, the spectral bandwidth of which was 2.5 THz.This high-gain broadband OPA module will help build an advanced information society.

Wavelength shifting and amplification of optical pulses through cascaded second order processes in periodically-poled lithium niobate

Gian Piero Banfi, P.K. Datta, Vittorio Degiorgio +1 more

We report on wavelength-shifting based on cascaded second-order nonlinearities1 in periodically-poled lithium niobate. Wavelength shifting from a signal s at λs=λp+Δ to a frequency-shifted signal f at λf=λp−Δ is obtained under the action of a pump p at λp: the effect is realized through the generation of the second harmonic (sh) of p and subsequent parametric amplification of s driven by sh. In the latter process f is also generated. Exploiting the advantages of quasi-phase-matching, efficient shifting is achieved at pump intensities about two orders of magnitude lower than in traditional second-order materials such as BBO.2

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.

We review the capabilities of optical parametric amplifiers based on periodically poled lithium niobate (PPLN) waveguides for applications in optical communications and quantum information processing. In particular, we discuss recent advances in wavelength-band conversion, broadband amplification, and the generation of squeezed and non-Gaussian states of light. These advances demonstrate the versatility of PPLN-based devices as essential components for future optical networks and optical quantum computing systems.
