Coupling Between Silicon Waveguide and Metal-Dielectric-Metal Plasmonic Waveguide with Lens-Funnel Structure
摘要： Various photonic integrated components have been implemented by ultra-thin silicon-on-insulator (SOI) waveguides; therefore, it is desirable to couple ultra-thin SOI waveguides to plasmonic waveguides. In this paper, we present an ultra-thin SOI waveguide to a metal-dielectric-metal plasmonic waveguide based on a lens-funnel structure consisting of truncated Luneburg lens and metallic parabolic funnel. The lens is implemented by varying the guiding layer thickness. The effect of different parameters of the coupler’s geometry is studied using the finite-difference time-domain method. The 1.13-μm-long coupler improves the average coupling efficiency in the C-band from 66.4 to 82.1%. The numerical simulations indicate that the coupling efficiency is higher than 69% in the entire O, E, S, C, L, and U bands of optical communication.

摘要： For further increase of data rate in multimode fiber (MMF) links widely deployed in datacenters, wavelength division multiplexing (WDM) transmission technology is expected to be introduced. In this paper, we propose a Y-branched polymer waveguide with graded-index core for optical coupler in the MMF WDM links. The low loss structure of the Y-branched polymer waveguide is designed applying BPM simulation, and designed waveguide structures are actually fabricated using an imprint method to confirm their applicability to a low-loss optical coupler in MMF WDM links.

摘要： This paper experimentally demonstrates a low loss inter-chip coupler with coupling loss below 1dB utilizing inverse-taper coupling from a wafer scale silicon photonic interposer, designed to distribute laser emission to 100 photonic integrated circuit dies (PICs) with equal power and phase. During the packaging, PICs are flip-chip bounded onto the interposer to achieve electrical, optical, and thermal coupling.

RADIATION FIELD AND OPTICAL COUPLING EVALUATION USING A NEW MATHEMATICAL MODEL
摘要： The mathematical model elaborated in this paper is based on the concept of intrinsic modes in order to analyze and synthesize optical wave propagation along a non-uniform optical structure which is used in integrated optics communication as tapered optical coupler. The new mathematical model is simply developed by introducing modi?cations to the intrinsic integral, and its numerical evaluation illustrates the electromagnetic ?eld distribution inside a taper thin ?lm and also outside the waveguide constituted by the substrate and the cladding of lower refractive index. The proposed method permits e?ciently tracking the behaviour of the optical waves both inside and outside the optical waveguide, and quantifying the radiation and optical coupling occurring from the taper thin ?lm of higher refractive index to adjacent mediums until a total energy transfer; this happens at thicknesses lower than waveguide cuto? thickness of each mode. The new model can be applied to all types of tapered optical coupler, made from di?erent optical materials and having di?erent wedge angles.
