Two-mode division multiplexing in a silicon-on-insulator ring resonator

Abstract: Mode-division multiplexing (MDM) is an emerging multiple-input multiple-output method, utilizing multimode waveguides to increase channel numbers. In the past, silicon-on-insulator (SOI) devices have been primarily focused on single-mode waveguides. We present the design and fabrication of a two-mode SOI ring resonator for MDM systems. By optimizing the device parameters, we have ensured that each mode is treated equally within the ring. Using adiabatic Bezier curves in the ring bends, our ring demonstrated a … Show more

“…It should be remarked that although the insertion losses of the second-example device are somewhat high, they are acceptable in view of its very compact size of about L = 55Λ min = 17 µm, which is almost an order of magnitude smaller than that of traditional demultiplexers [3], [13]. The design of this example seems to be more practical than that of three TE modes, given in Example 1.…”

“…Luo et al have shown the first microring-based on-chip WDM-compatible mode-division multiplexing with low modal crosstalk and loss [11]. Dorin and Ye have presented a design and fabrication of a two-mode SOI ring resonator for MDM systems [13]. Gui et al have fabricated an on-chip two-mode multiplexer/demultiplexer using a tapered asymmetrical grating-assisted contra-directional coupler-based [18].…”

“…Many promising approaches have been reported for MADM including asymmetric directional couplers (ADCs) [9][10][11], single-mode microring- [12] and multimode microring-based [13] couplers, asymmetric Y-junctions [14][15][16][17] and topology optimized mode (de)multiplexer [18]. Most of the functional elements for MDM networks have already been demonstrated.…”

“…SOI mode (de)multiplexers using asymmetric Y junction or tapered asymmetrical directional couplers (ADCs) based on mode evolution have been demonstrated [12][13][14][15][16]. However, their fabrication is a big problem because a smooth tapered structure is still difficult to achieve precisely now.…”
