Abstract

Summary form only given. Optical frequency division by 3 is a critical step in realizing optical frequency counting in ultrahigh precision measurements. We report the efficient implementation of a 3:1 frequency divider by two back-to-back difference-frequency mixing (DFM) interactions using a double-grating structure in periodically poled lithium niobate (PPLN).

Optical frequency division by 3 of 532??nm in periodically poled lithium niobate with a double grating

P. Nee, N. C. Wong

Optical frequency division by 3 of 532 nm is demonstrated by back-to-back difference-frequency generation in a periodically poled lithium niobate crystal with a double grating. The first grating generates 1596-nm light from 532- and 798-nm inputs, and the second grating mixes the 798-nm input and the 1596-nm output from the first grating to produce a second 1596-nm output. The beat signal between the two 1596-nm outputs is detected and frequency stabilized to yield the 3:1 frequency ratio.

3:1 optical frequency division by difference-frequency mixing in periodically poled lithium niobate

P. Nee, N. C. Wong

We report on the demonstration of optical frequency division by 3 via two successive stages of difference frequency generation. Two input sources at 532 nm and 798 nm generated an output at 1596 nm and the mixing between the 798-nm input and the 1596-nm output generated a second 1596-nm output. Both difference frequency mixing stages were implemented in a single piece of quasi-phase matched periodically poled lithium niobate. By measuring the beat frequency between the two 1596-nm an exact frequency ratio of 3:2 was obtained between two input sources. A signal-to-noise ratio of 27 dB was obtained for a resolution bandwidth of 100 kHz.

Optical Nonlinear Processing Using PPLN

M. M. Fejer

Optical-frequency mixing can accomplish a variety of wavelength-and time-domain all-optical signal processing functions. Operation at speeds up to 160 Gb/s, bandwidths of 70 nm, and with as few as 400-photon pulses have been demonstrated in periodically-poled lithium niobate (PPLN) devices.

PPLN-Based Flexible Optical Logic and Gate

Jian Wang, Junqiang Sun, Qizhen Sun +4 more

All-optical flexible 20-Gb/s logic and gate based on cascaded sum- and difference-frequency generation in a periodically poled lithium niobate waveguide is proposed and experimentally demonstrated. The theoretical analyses further indicate that 40-, 80-, and 160-Gb/s ultrahigh-speed logic and operations can potentially be performed. Moreover, it is expected that the and output can be tuned in a wide wavelength range (67 nm) with slight fluctuation of the Q-factor and extinction ratio.
