Broadband On-Chip Three Mode (De) Multiplexer Using SWG-Asymmetric Adiabatic Coupling

A broadband and ultracompact on-chip three-mode (de)multiplexer has been designed and demonstrated experimentally using a subwavelength grating-assisted asymmetric adiabatic coupler on the silicon-on-insulator platform. The device supports the (de)multiplexing of TE0, TE1, and TE2 modes for a broad bandwidth of 145 nm. The proposed device has a compact footprint of

$\sim ~5\times 62~\mu $

m2. The fabricated device has a crosstalk of

$\lt -10$

dB and insertion loss of <2.6 dB for wavelengths 1530 - 1675 nm (C-L-U band). The proposed three-mode (de)multiplexer is beneficial for mode division multiplexing and can be used for bandwidth enhancement in photonic network-on-chip systems.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
