“…Photonic devices could be realised by the controlling of coupling loss and waveguide parameters, so that the signal coming from source (Light emitting diode) would reflect at the destination (photo detector) without any loss in the inter-medium stage. Since photonic based interconnects play an important role for designing an efficient device, many works relating to the same have done with the help of different types of photonic crystal waveguides [1][2][3][4][5][6][7][8][9][10]. For example; optical printed circuit board is addressed in the reference [1], where authors focuses on planar graded index waveguide along with the fabrication techniques.…”

The present research focuses on two dimensional L-shape waveguide for the realisation of optical interconnect at the signal of 1550 nm, which will help for the transformation of signals from one chip to another. In this article, graphene based light emitting diode generates the wavelength of 1550 nm, where PIN photodiode converts the optical signal (wavelength 1550 nm) to its electrical counterpart. The proposed wave guide (11×11 silicon rods) with L shape defect allows the signal from source to detector. The principle of mechanism relies on the propagation of field along with the defect path which is made through finite difference time domain method. Moreover, there is no loss associated with the structure during the transformation of signals. The computational result infers that the efficiency of LED is about 99.98 % where the efficiency of photodiode is 99.94 %. Finally, the suggested silicon based waveguide acts as a good candidate for the realisation of an efficient optical interconnect.

“…Recently, explosive growth in data analytics applications such as cloud computing, video streaming and online gaming are leading to a convergence between datacenters and high-performance computing (HPC) systems [1][2][3]. To satisfy such demands, large-scale studies have been developed towards intra-datacenter optical interconnects based on the silicon photonics platform via single mode fibers (SMF) in the last one kilometer [4,5].…”

Novel Low-Loss Fiber-Chip Edge Coupler for Coupling Standard Single Mode Fibers to Silicon Photonic Wire Waveguides

et al. 2021

Fiber-to-chip optical interconnects is a big challenge in silicon photonics application scenarios such as data centers and optical transmission systems. An edge coupler, compared to optical grating, is appealing to in the application of silicon photonics due to the high coupling efficiency between standard optical fibers (SMF-28) and the sub-micron silicon wire waveguides. In this work, we proposed a novel fiber–chip edge coupler approach with a large mode size for silicon photonic wire waveguides. The edge coupler consists of a multiple structure which was fulfilled by multiple silicon nitride layers embedded in SiO2 upper cladding, curved waveguides and two adiabatic spot size converter (SSC) sections. The multiple structure can allow light directly coupling from large mode size fiber-to-chip coupler, and then the curved waveguides and SSCs transmit the evanescent field to a 220 nm-thick silicon wire waveguide based on the silicon-on-insulator (SOI) platform. The edge coupler, designed for a standard SMF-28 fiber with 8.2 μm mode field diameter (MFD) at a wavelength of 1550 nm, exhibits a mode overlap efficiency exceeding 95% at the chip facet and the overall coupling exceeding 90%. The proposed edge coupler is fully compatible with standard microfabrication processes.

“…Considering the levels of antenna deployment expected in the coming years, a great deal of importance will be placed on the ability of these access networks to facilitate scaling in terms of both data rate and number of connected users. From the perspective of DC network evolution, flexible optical technologies such as photonic switching and tunable laser sources are actively being researched [4,5] to help facilitate network scaling which is increasingly being driven by mobile user demands [6].…”
