“…Furthermore, the wavelength division multiplexing (WDM) [29,30], dense WDM (DWDM) [31,32], and coarse WDM (CWDM) [33,34] techniques are commonly used in telecommunications networks [43][44][45] to separate bandwidth into smaller channels. The optical bandwidth is demultiplexer in the receiver to implement the WDM technique in the optical network.…”

In this study, a new four channel de-multiplexer with a ring resonator design is proposed. The bus waveguide and drop waveguide that make up the Ring Resonator are ring-shaped. One bus waveguide and four drop waveguides in the proposed four channel demultiplexer architecture were created utilizing a photonic crystal ring resonator construction. With the resonance wavelengths for each channel in the range of 1552.4nm, 1553.2nm, 1554.1nm, and 1555.4nm, the suggested demultiplexer average quality factor was 7870.90, and its average transmission efficiency was 98.67%. The demultiplexer was created with a 0.8nm narrow channel spacing and a -15dB to -25dB crosstalk range. The proposed ring resonator structure is made of silicon, which has a refractive index of 3.47, a center wavelength ranges of 1550 nm, and a lattice constant that varies with the radius range of 540 nm. To examine the performance, one can simulate the suggested demultiplexer structure using the FDTD approach. The proposed project's 198.7 µm2 footprint is appropriate for DWDM applications.

“…The fabrication procedures are moreover compatible with a complementary metal-oxide-semiconductor (CMOS) technology which allows high-density integration of several photonic devices on a single chip [6]. In addition to the footprint of the device, SOI-based AWGs also offer low insertion losses and crosstalk in near-and mid-infrared [7] - [8]. Micro-scale Si waveguides provide ultra-low loss (∼ 0.1 dB/cm), polarization independency, and a wide wavelength range operation from 1.2 to 4.0 µm which is suitable for spectroscopy.…”

32-channel arrayed waveguide grating spectrometer (AWG) at 1800 nm is demonstrated on a 2-µm-thick silicon-on-insulator (SOI) platform. The design and simulation of the device are performed using the beam propagation method (BPM) and we obtain the 3-dB channel width, channel spacing, and extinction ratio of 1.16 nm, 1.56 nm, and 5.17 dB, respectively. The AWG demultiplexer can be applied in the central part of a spectrometer which is replacing in integrated optics a prism or a grating in conventional free-space optics.

One of the most common techniques for increasing data bitrate using the telecommunication system is to use dense wavelength division multiplexing (DWDM). However, the implementation of DWDM with more channels requires additional waveguide coupler devices and greater energy consumption, which can limit the system performances. To solve these issues, we propose a new approach for designing the demultiplexer using angled multimode interference (AMMI) in gallium nitride (GaN)–silica (SiO2) slot waveguide structures. SiO2 and GaN materials are selected for confining the infrared light inside the GaN areas under the transverse electric (TE) field mode. The results show that, after 3.56 mm light propagation, three infrared wavelengths in the C-band can be demultiplexed using a single AMMI coupler with a power loss of 1.31 to 2.44 dB, large bandwidth of 12 to 13.69 nm, very low power back reflection of 47.64 to 48.76 dB, and crosstalk of −12.67 to −15.62 dB. Thus, the proposed design has the potential for improving performances in the telecommunication system that works with DWDM technology.
