“…Shortcuts to adiabaticity that has been developed to optimize the quantum state transfer is successfully applied to reduce the length of mode MUX, while the broadband and robust merits are preserved [60][61][62]. This approach provides a pathway to design compact and robust photonics integrated devices [63][64][65].…”

Space-division multiplexing (SDM) technique has attracted increasing attentions recently, because it provides an effective way to increase transmission capacity. With the continuous and exponential increase in data demands, high-density integration of silicon photonic components is of significant interest in terms of link price, performance and power consumption. The multimode/mutlicore devices applied to achieve diverse functionalities are key building blocks to construct a chip-scale SDM system based on a silicon on insulator (SOI) platform. This study reviews the recent progress of multimode/multicore devices, which enable coupling, multiplexing/demultiplexing, transmitting switching, as well as modulation and detection. Based on these devices, a complete on-chip SDM system is constructed and discussed.

“…In order to maintain the robustness properties of shortcuts to adiabaticity, it is better to avoid waveguide lengths close to this minimum [18]. Yet, the necessary length is smaller than that required by devices based on purely adiabatic schemes [20][21][22][23].…”

In this article we use the method of shortcuts to adiabaticity to design a photonic lattice (array of waveguides) which can drive the input light to a controlled location at the output. The output position in the array is determined by functions of the propagation distance along the waveguides, which modulate the lattice characteristics (index of refraction, first and second neighbor couplings). The proposed coupler is expected to posses the robustness properties of the design method, coming from its adiabatic nature, and also to have a smaller footprint than purely adiabatic couplers. The present work provides a very interesting example where methods from quantum control can be exploited to design lattices with desired input-output properties.

“…Recently, tunable mode conversions are implemented by utilizing the acousto-optic effect in optical fibers 5 6 7 , which is useful in mode division multiplexing (MDM) over multi-mode fibers. Meanwhile, the on-chip mode converter, serving as an important device to add and drop optical signals, has also been proposed as an important component in the integrated MDM systems 8 9 10 . At present, the main methods using for on-chip mode converter are adiabatic coupling and resonant coupling.…”

We present a scheme for reversible and tunable on-chip optical mode conversion based on dynamic grating in a hybrid photonic-phononic waveguide. The dynamic grating is built up through the acousto-optic effect and the theoretical model of the optical mode conversion is developed by considering the geometrical deformation and refractive index change. Three kinds of mode conversions are able to be realized using the same hybrid waveguide structure in a large bandwidth by only changing the launched acoustic frequency. The complete mode conversion can be achieved by choosing a proper acoustic power under a given waveguide length.
