Electro‐optic conversion circuit incorporating a fiber optic loop for light fidelity up‐down link use

Abstract

We propose the use of the electro‐optic circuit to integrate with the short distance fiber optic loop network, which can be used to form the light fidelity (LiFi) network platform within the building. The electro‐optic conversion circuit is formed by a plasmonic circuit. It is a passive device consisting of an embedded plasmonic island within the microring conjugate mirror (MCM), in which the applied input‐output information can be connected to the fiber optic loop. In this design, all sources of the information can be coupled to the plasmonic transducer and connected to the network. The transducer mobility and two different wavelengths of the input sources are demonstrated and all port signals plotted. The free spectral range and the full‐width at half maximum at the center wavelength of 1.30 μm are ~370.0 and ~0.62 nm, respectively. This is equal to the bandwidth of ~77 PetaHz, from which the output intensity power is ranged between 5 and 15 mW (μm)−2. The linear relationship between the driven mobility and the input power of ~0.75 (cm)2. (Vs)−1 W−1 is achieved at the drop port, with the gold layer length is 600 nm.

High-Density Wavelength Multiplexing Model for THz-EMI Transmission

“…The required outputs are the combination of signal bandwidths and the whispering gallery mode (WGM), in which the up and down link of the system (LiFi) can be linked by the free-space WGM transmission. The other fields propagating within the system in Z-axis are presented as follow [23,34].…”

“…The LiFi system requires the large bandwidth to accommodate the big data transmission, from which the combination of microring resonators can offer such a requirement. The other forms of the LiFi networks can be found in the references [23][24][25]. Moreover, the use of the new material such as chalcogenide glass has been reported the promising results that the wide range of the transmission can be covered the wireless transmission wavelengths [26,27], which can offer the broader range from light to radio waves.…”

Optimum light transmission via microring resonator under a lossy‐coupler critical coupling condition

“…Microring resonators have been receiving considerable attention due to their specific characteristics, including microscale, compatibility to integrate with complementary metaloxide-semiconductor (CMOS) technology, generating sharp resonance peaks, and low cost of fabrication that make them as potential building blocks for the next generation of chipscale photonic integrated circuits. Today, microring resonators are practical devices for optical routing, 1 modulator and logic gate, optical signal processing, [2][3][4] optical sensors, 5,6 all-optical switching, 7,8 light fidelity technology, 3 nonlinear optics, [9][10][11] optical gyroscope, 12 multiplexing 13 and demultiplexing, 14 wavelength filtering 15,16 and modulation applications. 17 In ring resonators, the input wave interference with the relative delay circulated waves via each coupler and brings about the filtering function, which is quite desirable in optical communications and optical sensing applications.…”

Double critical coupled ring resonator-based add–drop filters

“…Integrated ring resonators have found a number of usages in integrated optics due to their compact size, low cost of fabrication and their ability to integrate with on chip circuits. Today, micro-size resonators are practical devices for switching [2][3][4], multiplexing, demultiplexing [5] and wavelength filtering [6,7], modulation applications [8], wide band antenna [9,10], modulator and logic gate in optical signal processing [11,12], and sensitive sensors and biosensors [13][14][15]. One of the primary applications of ring resonators is their application as an add-drop notch type filter in optical networks.…”
