“…Silicon grating structures are more widely used material for designing the filters where the thicknesses of the semiconductor materials are the deciding factor to allow the desired wavelength of the light signal. In the literature [1][2][3][4][5][6][7], most of the filters are designed by taking the alternate combination of Silicon (Si) and Silicon Monoxide (SiO) with some defect. Total 64 layers of Si and SiO are taken with some appropriate which decides the allowable wavelength of light signals.…”

A vehicular control system operated in VLC spectrum is envisaged in this work which is control by optical monochromatic filters. Overall six numbers of monochromatic optical filters are designed by the help PWE simulation method by considering silicon grating structure (Si and SiO) as background semiconductor material to control the direction of the vehicular system. Further, Matlab Simulink is implemented to realize the different direction with the degree of angular rotation while moving in left and right direction. In the simulation process, Arduino board is used to receive the control signals from the filters through the photo detectors and then according to the program stored in the memory, the outputs are actuated to drive the vehicular system corresponding to each combination of the inputs.

“…The demux device has several advantages such as a low bit error rate [ 3 ], a high data rate, a large bandwidth, low cross-talk [ 4 ], and less propagation delay. Therefore, researchers have shown the potential of designing demux-based waveguide techniques such as silicon photonics [ 5 ], Y-branch [ 6 ], multimode interference (MMI) [ 7 , 8 , 9 ], Mach–Zehnder interferometers [ 10 , 11 ], MMI in slot waveguide structures [ 12 , 13 , 14 ], etc.…”

A novel eight-channel demux device based on multicore photonic crystal fiber (PCF) structures that operate in the C-band range (1530–1565 nm) has been demonstrated. The PCF demux design is based on replacing some air-hole areas with lithium niobate and silicon nitride materials over the PCF axis alongside with the appropriate optimizations of the PCF structure. The beam propagation method (BPM) combined with Matlab codes was used to model the demux device and optimize the geometrical parameters of the PCF structure. The simulation results showed that the eight-channel demux can be demultiplexing after light propagation of 5 cm with a large bandwidth (4.03–4.69 nm) and cross-talk (−16.88 to −15.93 dB). Thus, the proposed device has great potential to be integrated into dense wavelength division multiplexing (DWDM) technology for increasing performances in networking systems.

A novel 8-channel demux device based on multicore photonic crystal fiber (PCF) structures that operate at C-band range (1530-1565nm) has been demonstrated. The PCF demux design is based on replacing some air-holes areas with lithium niobate and silicon nitride materials over the PCF axis alongside with the appropriate optimizations of the PCF structure. The beam propagation method (BPM) combined with Matlab codes were used to modeled the demux device and to optimized the geometrical parameters of the PCF structure. Simulation results show that 8-channel can be demultiplexing after light propagation of 5 cm with large bandwidth (4.03-4.69nm) and crosstalk ((-16.88)-(-15.93) dB). Thus, the proposed device has a great potential to be integrated in dense wavelength division multiplexing (DWDM) technology for increasing performances in networking systems.
