“…The paper quantifies the intermodal energy transfer of the fundamental mode in 125 µm diameter fiber and the practical limits of the tapering angle are determined. 35 Adiabaticity of higher order modes as a function of taper angle for 80 µm and 50 µm diameter fiber is discussed elsewhere. 33,36 …”

“…The spectrogram of the Fourier analysis reveals the beating between the different modes. 28,35 First, the transmission of the mode during the fabrication of a tapered fiber with an exponential profile was studied. Unlike for the fundamental fiber mode, the taper angle dependence is much stronger for the mode, i.e., low loss occurs for shallower angles.…”

“…The most common way of fabricating such a tapered fiber is by heating and stretching a section of standard optical fiber in a flame. [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] The flame can either be stationary, 24,28,33 brushed, [18][19][20][21]23,25,29,31,[34][35][36] or one can use a simulated flame brush, [26][27]32 which relies on a stationary flame but oscillating stages. Most flame setups use either an oxy-butane 33,34 or oxy-hydrogen torch.…”

We review the method of producing adiabatic optical micro-and nanofibers using a hydrogen/oxygen flame brushing technique. The flame is scanned along the fiber, which is being simultaneously stretched by two translation stages. The tapered fiber fabrication is reproducible and yields highly adiabatic tapers with either exponential or linear profiles. Details regarding the setup of the flame brushing rig and the various parameters used are presented. Information available from the literature is compiled and further details that are necessary to have a functioning pulling rig are included. This should enable the reader to fabricate various taper profiles, while achieving adiabatic transmission of ~ 99% for fundamental mode propagation. Using this rig, transmissions ranging from 85-95% for higher order modes in an optical nanofiber have been obtained.

“…We find the expected transmission to be consistent with our experimental result that measures the transmission through the entire ONF. Furthermore, when launching the next family of modes (LP 11 ) through the fiber the FIMMPROP simulations are well-matched to the achieved transmissions in Ravets et al (2013a).…”

“…The sudden large change from guiding with small V -number (V ≈ 2) to large V -number (V ≈ 100) represents a mode volume change of more than 1000. It is this region that places the most stringent requirements on adiabatic propagation, as described in analytical treatments Frawley et al (2012b); Ravets et al (2013a); Nagai and Aoki (2014).…”

The development of optical nanofibers (ONF) and the study and control of their optical properties when coupling atoms to their electromagnetic modes has opened new possibilities for their use in quantum optics and quantum information science. These ONFs offer tight optical mode confinement (less than the wavelength of light) and diffraction-free propagation. The small cross section of the transverse field allows probing of linear and non-linear spectroscopic features of atoms with exquisitely low power. The cooperativity -the figure of merit in many quantum optics and quantum information systems -tends to be large even for a single atom in the mode of an ONF, as it is proportional to the ratio of the atomic cross section to the electromagnetic mode cross section. ONFs offer a natural bus for information and for inter-atomic coupling through the tightly-confined modes, which opens the possibility of one-dimensional many-body physics and interesting quantum interconnection applications. The presence of the ONF modifies the vacuum field, affecting the spontaneous emission rates of atoms in its vicinity. The high gradients in the radial intensity naturally provide the potential for trapping atoms around the ONF, allowing the creation of onedimensional arrays of atoms. The same radial gradient in the transverse direction of the field is responsible for the existence of a large longitudinal component that introduces the possibility of spin-orbit coupling of the light and the atom, enabling the exploration of chiral quantum optics.

Being a new class of two dimensional (2D) metal carbides, borides, and nitrides, MXenes comprise one of the largest families of 2D nanomaterials that provide huge possibilities in photonics, electronics, and energy, Particularly, MXenes are discovered recently as alternatives to conventional saturable absorbers (SAs), such as carbon nanotube and graphene, which are used for short laser pulse generation. The high saturable absorption, astounding modulation depth, flexible bandgap tunability, and high electron density near Fermi level are the main features that make MXenes excellent candidate materials for SAs. Herein, this review summarizes the recent development on synthesis and characterization of the MXene, with focus on the nonlinear saturable absorption and the application of the MXene SA in mode‐locked fiber lasers. The emerging issues and challenges associated with MXene based SAs, as well as future perspectives of the reviewed topic are also discussed.
