Optical parametric oscillator based on degenerate four-wave mixing in suspended core tellurite microstructured optical fiber

Abstract

We report on a suspended core tellurite microstructured optical fiber (TMOF) based optical parametric oscillator (OPO). The intracavity gain is provided by the degenerate four-wave mixing (DFWM) occurred in a 1.5-m-long TMOF synchronously pumped by a mode-locked picosecond erbium-doped fiber laser. The oscillated signal can be generated from 1606 nm to 1743.5 nm, and the idler can be emited from 1526.8 nm to 1395 nm by adjusting the pump wavelength from 1565.4 nm to 1551 nm. A total intenal conversion efficiency of -17.2 dB has been achieved.

Analysis of spectral broadening dominated by cascaded stimulated Raman scattering in optical fibers

“…As pump wavelength is near ZDW, the side lobes' bandwidth increases and shifts closer to the pump. This has been demonstrated for conventional optical fibers used in this work, and in microstructured fiber [18], highly nonlinear optical fibers and dispersion-shifted fiber [19]. Moreover, Fig.…”

Broadband optical parametric amplifier formed by two pairs of adjacent four-wave mixing sidebands in a tellurite microstructured optical fibre

“…Figure 2 shows the optical parametric fluorescence spectrum with two pairs of FWM sidebands generated in the TMOF for the pump at 1554.1 nm with a peak power of 30 W (the corresponding average power is 12.9 dBm). It can be seen that the intensity of the signal (shorter than the pump) of the outer pair of FWM sidebands is similar to that of the inner pair [30]. The intensity of the idler (longer than the pump) of the outer pair is larger than that of the inner pair, which is attributed to the contribution of the Raman amplification effect.…”

“…An FOPA operated in the S band with a peak gain of 90.2 dB has been reported in a TMOF with the ZDW located at 1570 nm pumped by a nanosecond laser [29]. In another TMOF with the ZDW located at 1560 nm, an optical parametric oscillator (OPO) operating from 1395 to 1743.5 nm has been demonstrated [30]. In the OPO experiment, we found that two pairs of adjacent FWM can be generated in the TMOF for the pump at 1554.1 nm.…”

High-energy dissipative soliton-driven fiber optical parametric oscillator emitting at 1.7 µm

“…However, the soliton energy scaling law calls for the use of large-mode-area rod-type fibers, making these sources bulky. FOPOs represent an interesting alternative for ultrashort pulse generation with a tailored bandwidth in this spectral range [20][21][22]. In particular, the exploitation of a normal dispersion FOPO has enabled energy scaling beyond the nanojoule barrier around 1700 nm with a broad tuning range.…”
