“…Also, an all-in-fiber switch or modulator is more desirable to be compatible with a standard fiber-optic system in real applications. Unfortunately, limited by silica's intrinsically low nonlinear optical responses, significantly high optical powers, large fiber lengths, or high chalcogenide/ytterbium doping, are required to induce moderately strong all-optical effects in optical fibers for all-optical switches [5][6][7].…”

Recently, the integration of two-dimensional materials with optical fibers has opened up a great opportunity to develop all-fiber signal-processing devices. Graphene is an ideal material for all-optical signal processing via thermal-optic effect because of its high electrical and thermal conductivity, as well as broadband light-matter interactions with fast responses. Herein, we report the achievement of all-optical switching with fast response by integrating few-layer graphene onto a tilted fiber Bragg grating (TFBG) inscribed in a reduceddiameter fiber. Relying on graphene's decent photothermal effect, the transmission spectrum of the TFBG could be alloptically modulated by tuning the incident pump power. The all-optical switch can consequently operate at a series of wavelengths owing to the TFBG's comb-like resonances. The reduced diameter of the graphene-integrated TFBG and the pump at its resonant wavelength promise the alloptical switch to have a fast-dynamic response of around 1 s and an extinction ratio exceeding 13 dB. This compact device with graphene integration has the potentials to be integrated into all-fiber system to extend the functions of all-optical signal processing.

This article demonstrated the Au nanoparticles-doped polymer all-optical switches based on photothermal effects. The Au nanoparticles have a strong photothermal effect, which would generate the inhomogeneous thermal field distributions in the waveguide under the laser irradiation. Meanwhile, the polymer materials have the characteristics of good compatibility with photothermal materials, low cost, high thermo-optical coefficient and flexibility. Therefore, the Au nanoparticles-doped polymer material can be applied in optically controlled optical switches with low power consumption, small device dimension and high integration. Moreover, the end-pumping method has a higher optical excitation efficiency, which can further reduce the power consumption of the device. Two kinds of all-optical switching devices have been designed including a base mode switch and a first-order mode switch. For the base mode switch, the power consumption and the rise/fall time were 2.05 mW and 17.3/106.9 μs, respectively at the wavelength of 650 nm. For the first-order mode switch, the power consumption and the rise/fall time were 0.5 mW and 10.2/74.9 μs, respectively at the wavelength of 532 nm. This all-optical switching device has the potential applications in all-optical networks, flexibility device and wearable technology fields.

“…Furthermore, due to the use of continuous-wave (CW) signal and idler, the effects of pulse breakup and walk-off existing in the PI all-optical switch can be significantly mitigated. Therefore, the fiber-based PS all-optical switch might be an attractive and promising all-optical device in future energy-efficient optical networks [17]. However, a FOPA is a distributed optical amplifier and the FWM effect is sensitive to the local phase matching [13].…”

A fiber-based all-optical switch accomplished by pump depletion in a single-pump phase sensitive (PS) amplifier is theoretically investigated using an inhomogeneous fiber model including the zero-dispersion wavelength (ZDW) fluctuations. We find that the OFF-state (maximum pump depletion) of the PS alloptical switch is very sensitive to the ZDW fluctuations, whereas the ON-state (minimum pump depletion) is more robust. Meanwhile, the nonreciprocal transmission characteristic of the PS all-optical switch induced by the ZDW fluctuations is investigated with the help of the proposed inhomogeneous fiber model. Our theoretical results are useful to optimize the experimental implementation of PS all-optical switch.
