“…Owing to the absence of diffraction effects and strict optical limitations, optical fibers have proven highly efficient for spectral broadening and the generation of DWs 38,40 . The ring-core optical fiber, in particular, offers enhanced freedom in dispersion engineering and serves as an ideal medium for the stable transmission of OAM modes.…”

Beams carrying orbital angular momentum (OAM) have exhibited significant potential across various fields, such as metrology, image coding, and optical communications. High-performance broadband coherent OAM sources are critical to the operation of optical systems. The emission of dispersive waves facilitates the efficient transfer of energy to distant spectral domains while preserving the coherence among the generated frequency components. Light sources that maintain consistency over a wide range can increase the efficiency of optical communication systems and improve the measurement accuracy in imaging and metrology. In this work, we propose a germanium-doped double ring-core fiber for five OAM dispersive waves (DWs) generation. The OAM1,1 mode supported in the fiber exhibits three zero-dispersion wavelengths (ZDWs) located at 1275, 1720 and 2325 nm. When pumped under normal dispersion, the output spectrum undergoes broadening and exhibits five DWs, situated around 955, 1120, 1450, 2795 and 2965 nm, respectively. Concomitant with blue-shifted and red-shifted dispersive waves, the spectrum spans from 895 to 3050 nm with high coherence. The effect of the fiber and input pulse parameters on DWs generation, as well as the underlying dynamics of the dispersive wave generation process, are discussed. As expected, the number and location of DWs generated in the output spectrum have agreement with the prediction of the phase-matching condition. Overall, this multiple DWs generation method in the proposed fiber paves the way for developing efficient and coherent OAM light sources in fiber-based optical systems.

“…[76] In a later work, Scheibinger et al highlight the use of temperature tuning in a more sophisticated dispersion landscape featuring multiple zero-dispersion wavelengths of selected low-order waveguide modes.

Softphotonics has emerged as a new discipline that utilizes soft matter (i.e., liquids, gels, bio‐materials) as waveguide materials with versatile functionalities. The flexible properties of soft matter show great potential for further exploiting nonlinear in‐fiber phenomena to gain more insights into their fundamental dynamics and to inspire a new generation of broadband optical light sources and signal processors that are adaptable, reconfigurable, and biocompatible. In particular, incorporating solvents with extraordinary temperature sensitivity, miscibility, and nonlinearity into optical fibers has spawned a series of inventions and fundamental scientific findings over the last decades. This review highlights the current state of development of nonlinear photonics in liquid‐filled fibers. The current state of knowledge in the linear and nonlinear material properties of the most prominent solvents (CS2, CCl4, C2Cl4, benzene and its derivatives) are revisited, and recent advances in nonlinear liquid‐core fiber optics, including a special highlight on phenomena that are unique to liquids, such as modified solitary states and local dispersion control are summarized. Finally, the leading scientific challenges for advancing the field, which highlights liquid‐core fibers as a rich platform for science and technology, are discussed.

Here, the concept of generating higher‐order dispersive waves (DWs) via quasi‐phase‐matching (QPM) in periodically dispersion‐modulated liquid‐core fibers are demonstrated by generating distinct narrowband sidebands generated outside the conventional supercontinuum (SC) spectrum. Through controlled partial core collapse, the commonly used phase‐matching (PM) condition is amended by an additional grating‐related term. This results in the generation of ultrashort higher‐order DWs controlled by the grating parameters, extending the conventional SC spectrum up to 3 . Of particular interest is the excellent overlap of the QPM‐peaks obtained from experiments, simulations, and PM considerations, showing the quality of the implementation approach and allowing for controlled narrowband peaks generation even for femtosecond input pulses. In summary, this multicolor generation concept embodies a versatile photonic platform with unique dispersion control capabilities for the transfer of spectral power into selected narrowband spectral intervals. It stands out with its unique capabilities, making it well‐suited for applications in diverse fields like bioanalytics, life sciences, quantum technology, and metrology.
