Improved Design of 8-Channel Silicon-on-Insulator (SOI) Arrayed Waveguide Grating (AWG) Multiplexer Using Tapered Entry into the Slab Waveguides

Abstract

An improved design of silicon-on-insulator based 8 × 8 AWG multiplexer is presented using tapered entry into the slab waveguide. Our simulation result clearly shows significant enhancement of electric field from 0.44 V/m to 0.732 V/m, reduction in insertion loss from 7.13 db to 2.7 db, with bandwidth of 230 GHz and channel spacing 200 GHz while keeping other parameters within acceptable limits.

Performance study of silica-on-silicon based multimode interference (MMI) optical coupler

“…That is, the wavelength is 1.55 µm, the refractive indices of the core and cladding are 1.46 and 1.456, respectively, the thickness of the guiding layer and the width of the access waveguide are both 6 µm, and the selected widths of the multimode waveguide are 90 µm, 100 µm, 110 µm, 120 µm, 130 µm and 140 µm. For different widths of the multimode waveguide, mmi L varies within the range found using (7) and (8). Calculations are done for widths of 90 µm, 100 µm, 110 µm, 120 µm, 130 µm, and 140 µm, which corresponded to 10, 11, 12, 13, 14 and 15 modes respectively in the multimode waveguide.…”

“…[2] However, many of these problems have been solved, leaving PLCs with four major advantages: the enhanced functionality, very low losses, compactness, and potential for the mass production. Generally, PLCs based optical waveguides and devices can be fabricated by using different materials including LiNbO 3 [3], SiO 2 [4,5], silicon-on-insulator (SOI) [6,7], polymer [8], InP [9,10]. Each material has advantages and disadvantages for a specific required function.…”

“…Their basic working principle is the total internal reflection of light. Optical waveguides and devices can be fabricated by using different materials including LiNbO 3 [3], SiO 2 [4,5], Silicon on Insulator (SOI) [6,7], Polymer [8], InP [9,10], etc. Fiber-to-the-home (FTTH) networks have been considered to be the ultimate solution for future broadband access networks.…”
