“…The Green's function SVD process of Eq. (6) is similar to that previously used to find temporal [8][9][10][11][12] modes of parametric amplifiers and wavelength converters and spatial [13][14][15][16] modes of parametric image amplifiers [17]. Functions u ij (x) are orthonormal:…”

We analyze sum-frequency generation (SFG) in a χ (2) slab waveguide with the goal of achieving a single spatial-mode operation. We first develop Green's function formalism for the SFG equations and then perform singular-value decomposition (SVD) of the Green's function. By adjusting the spatial profile of the pump, we manipulate the SVD spectrum to maximize the up-conversion of one signal mode while minimizing the up-conversion of all others, which opens a possibility of realizing a spatial-mode-selective quantum frequency converter for future optical communications.

Space-division multiplexing: the next frontier in optical communication

Space-division multiplexing (SDM) uses multiplicity of space channels to increase capacity for optical communication. It is applicable for optical communication in both free space and guided waves. This paper focuses on SDM for fiber-optic communication using few-mode fibers or multimode fibers, in particular on the critical challenge of mode crosstalk. Multiple-input-multipleoutput (MIMO) equalization methods developed for wireless communication can be applied as an electronic method to equalize mode crosstalk. Optical approaches, including differential modal group delay management, strong mode coupling, and multicore fibers, are necessary to bring the computational complexity for MIMO mode crosstalk equalization to practical levels. Progress in passive devices, such as (de)multiplexers, and active devices, such as amplifiers and switches, which are considered straightforward challenges in comparison with mode crosstalk, are reviewed. Finally, we present the prospects for SDM in optical transmission and networking.

“…We employ modal phase matching [23]- [25] between 0 th -order mode of the near-infrared (1550-nm) fundamental wave and 2 nd -order mode of the SHG wave (775 nm). This technique is similar to the one previously used in SiN-surface-based SHG [20], and it builds upon our work on multimode parametric amplification [24], [26], [27] and mode-selective wavelength conversion [25], [28]- [30]. We numerically optimize the waveguide configuration to simultaneously achieve the phase matching and maximize the nonlinear overlap integral between the interacting waves.…”

Investigation of Hybrid Silicon-Nitride/Polymer Waveguides for Second-Harmonic Generation

et al. 2019

We propose a hybrid silicon-nitride (Si 3 N 4 or SiN for short)/nonlinear polymer waveguide to achieve second-harmonic generation of an input 1550 nm signal by modal phase-matching between zero-order spatial mode at 1550 nm and second-order mode at 775 nm. We explore and optimize two cases, single channel waveguide and slot waveguide, by varying the waveguide dimensions. For TE polarized light, the optimum slot waveguide exhibits an effective interaction area A eff of about 16 μm 2 , which is an order-of-magnitude improvement over the single channel waveguide and can translate to a high value of effective nonlinearity. We also show that the optimum slot waveguide geometry is robust with respect to fabrication uncertainties and bending effects.
