We demonstrate a high-efficiency intermodal four-wave-mixing process in an all-fiber system, comprising a picosecond fiber laser and a high-order-mode (HOM) fiber. Two pump photons in the LP 01 mode of the fiber can generate an anti-Stokes photon in the LP 01 mode and a Stokes photon in the LP 02 mode. The wavelength dependent mode profiles of the HOM fiber produce significant spatial overlap between the modes involved. The anti-Stokes wave at 941 nm is generated with 20% conversion efficiency with input pulse energy of 20 nJ. The guidance of the anti-Stokes and Stokes waves in the HOM fiber enhances system stability. V C 2012 American Institute of Physics.[http://dx.doi.org/10.1063/1.4759038] Four-wave mixing (FWM) in optical fibers has been utilized for nonlinear frequency conversion. FWM has been studied in single-mode fibers, multimode fibers, and more recently, photonic crystal fibers (PCFs). [1][2][3][4][5][6][7][8] In most experiments, the red-shifted Stokes wave and the blue-shifted antiStokes wave are generated within the same mode as the pump light. In these cases, the phase-matching conditions require the pump to be in the vicinity of the zero dispersion wavelength (ZDW) of the propagating mode. 8,9 However, launching high power pump light near the ZDW can easily generate a supercontinuum (SC), which limits the conversion efficiency from the pump to the narrow-band Stokes and anti-Stokes waves. 10 High-efficiency FWM generation at 673 nm and 2539 nm has been achieved in an endlessly single-mode large-mode-area (LMA) PCF without having the pump light close to the ZDW. 11 However, this approach cannot be extended to generate light at other wavelengths, since the phase-matching condition is predominantly defined by the material dispersion. To overcome the limitation of FWM within a single spatial mode, an intermodal FWM approach has been proposed. 12 In this approach, pump light is launched in the normal dispersion region of the fundamental mode. The Stokes and the anti-Stokes waves can satisfy the phase-matching condition by propagating in other higher-order-modes (HOMs). This effect has been observed in conventional and Ge-doped multimode fibers at visible wavelengths, using a high power pump at 532 nm. 3,4 Recently, the effect has been studied more systematically in PCFs. [12][13][14] Intermodal FWM has several advantages over traditional single-mode FWM. This method can achieve high conversion efficiency without SC generation. 12 The wavelength of the Stokes and anti-Stokes light can be easily controlled by fiber design, such as changing the core diameter. 4,13 More importantly, intermodal FWM provides extra degrees of freedom, thus increased flexibility, in fiber designs to generate FWM, because the phase-matching condition can be fulfilled with more than one propagating mode. However, intermodal FWM demonstrations so far require a high-power laser source, such as a Q-switched Nd:YAG laser or a Ti:Sapphire regenerative amplifier. As a result, they are typically used to generate light with high pulse...

“…In addition to second order parametric interactions in nonlinear optical crystals [Mye95], the third-order nonlinear response of photonic crystal fibre has recently been exploited in the development of four-wave mixing (FWM)-based sources generating radiation in the visible spectral region [Har03,Nod09]. Graphene is emerging as a viable alternative to conventional nanomaterials and has been proven effective as an ultrafast switch, promoting mode-locking in ultrashort pulse lasers [Sun10a,Sun10b].…”

Nonlinear optics enables the manipulation of spectral and temporal characteristics of optical pulses interacting with a dielectric medium. Optical fibres, as a uniquely practical medium, provide an environment for effectively exploiting the nonlinear effects. This has facilitated the rapid growing interest in this field focused on the investigation of fibrebased sources incorporated with various novel saturable absorber devices for ultrashort pulse generation.This thesis reports a series of experiments exploring the ongoing research in the field of nonlinear optics, including the development of ultrafast mode-locked fibre sources and their applications in supercontinumm generation and third order parametric interactions in new carbon materials.Firstly, the integration of carbon-based materials with rare-earth doped media allows the demonstration of ultrafast mode-locked laser sources operating at wavelengths across the near-infrared region in a compact, low cost and environmentally robust scheme.Power scaling of such sources can be achieved by operating in the all-normal dispersion regime making use of a glass-substrate saturable absorber device that exhibits a higher damage threshold.Supercontinuum generation has been used as an effective method for spectral broadening. Pumping with a conceptually simple and reliable fibre-based system, a continuum covering from 2 to 3 µm is generated in a highly nonlinear GeO 2 fibre. This experiment demonstrates a robust and long-term stable source of radiation in an important band, coincident with a portion of the atmospheric transmission window.Finally, the demonstration of a simple and compact nano-material based dual-wavelength system shows the performance of such devices as a simultaneous saturable absorber and passive synchroniser. An experimental study of coherent frequency mixing at large frequency shifts in a graphene sample, pumped by a two-colour fibre-integrated source, proves the strong nonlinear response of this new carbon material.

Abstract-A dual-core photonic crystal fiber (DC-PCF) is proposed, and bending characteristics of the DC-PCF are investigated. Two fiber cores are employed in the cross-section of the DC-PCF, which result in a mode coupling between the two fiber cores when the light propagates inside the DC-PCF. The mode coupling between two fiber cores of the DC-PCF is sensitive to the directional bending of the DC-PCF which essentially provides a method to achieve bending sensing. A DC-PCF-based bending sensor is proposed by injecting a broadband light into one fiber core of the DC-PCF on one side and detecting output spectrum from another fiber core of the DC-PCF on the other side. In our simulations, a parabola curve which shows the relationship between the wavelength shift of the transmission spectrum of the DC-PCF-based bending sensor and the bending curvature of the DC-PCF is presented.
