“…Low insertion losses increase the transmission span length without the need for optical amplification, low mode-dependent losses maximise the transmission capacity [149] and mode selectivity reduces the electronic single processing complexity [150]. These requirements can be met by photonic lanterns, mode-selective directional couplers [151] and mode-selective tapered velocity couplers [152]. Photonic lanterns can simultaneously multiplex a large number of modes [153].…”

Since the discovery that tightly focused femtosecond laser pulses can induce a highly localised and permanent refractive index modification in a large number of transparent dielectrics, the technique of ultrafast laser inscription has received great attention from a wide range of applications. In particular, the capability to create three-dimensional optical waveguide circuits has opened up new opportunities for integrated photonics that would not have been possible with traditional planar fabrication techniques because it enables full access to the many degrees of freedom in a photon. This paper reviews the basic techniques and technological challenges of 3D integrated photonics fabricated using ultrafast laser inscription as well as reviews the most recent progress in the fields of astrophotonics, optical communication, quantum photonics, emulation of quantum systems, optofluidics and sensing.

“…For free space optics, the desired mode is excited by the LP 01 mode using transversemode matched method with a phase management at the expense of the bulky volume [16][17][18][19]. For a fiber based converter, a long-period fiber grating (LPFG) has been proposed earlier to realize the LP 01 -LP 11 mode conversion [20][21][22][23]. The mode converter can also be realized by the evanescent coupling based on the phase matched condition for a fiber with two asymmetric cores [66,67] or a few cores [68,69].…”

“…In order to reduce the complexity, fewmode fibers have been developed and the few-mode (de)multiplexing is realized with some complicated free-space optical setups [16][17][18][19][20][21][22][23][24][25], which, however, is very difficult to extend to include additional modes. For photonic networks-on-chip, the situation becomes much better because multi-mode planar optical waveguides can be precisely fabricated to manage the propagation of multi-modes and some specific PICs can be designed to realize the conversion between the eigen-modes conveniently [14].…”

Abstract-Multimode spatial-division multiplexing (SDM) technology has attracted much attention for its potential to enhance the capacity of an optical-interconnect link with a single wavelength carrier. For a mode-multiplexed optical-interconnect link, the functional elements are quite different from the conventional ones as multiple modes are involved. In this paper we give a review and discussion on multimode photonic integrated devices for mode-multiplexed opticalinterconnects. Light propagation and mode conversion in tapered waveguides as well as bent waveguides are discussed first. Recent progress on mode converter-(de)multiplexers is then reviewed. The demands of some functional devices used for mode-multiplexed opticalinterconnects are also discussed. In particular, the fabrication tolerance is analyzed in detail for our hybrid demultiplexer, which enables mode-/polarization-division-(de)multiplexing simultaneously.

A new class of resonant exchange of power among three co-propagating modes in dielectric optical waveguides exhibiting Kerr-like nonlinearity is reported. Unlike the coupling of modes travelling in different, spatially separated channels as in the directional coupler (Jensen, IEEE J. Quantum Electron. QE-18 ( 1982) 1580; Chen, Snyder and Mitchell, Electron. Lett. 26 ( 1990) 77; Schmidt-Hattenberger, Trutschel and Lederer, Optics L&t. 16 (1991) 294) this paper points out the possibility of obtaining an efficient coupling of modes travelling in one single channel. The key point here is the imposition of a geometrical resonance between modes, to improve the coupling process. Due to this resonance condition, which is related with the wavelength through the propagation constants, the power exchange process is very sensitive to the wavelength.
