A study of discrete wavelet transform based denoising to reduce the effect of artificial light interferences for indoor optical wireless communication [PDF]

open access: yes, 2010
The optical power penalty (OPP) due to the artificial light interferences (ALIs) can be significantly high in an indoor optical wireless communication (OWC) channel making such link practically infeasible.

Experimental demonstration of dual-polarization multiplexed optical phased array empowered by inverse design. [PDF]

open access: yesNanophotonics
Abstract This paper presents a dual‐polarization multiplexed optical phased array (OPA) implemented on a 220 nm silicon‐on‐insulator (SOI) platform, enabling continuous beam steering across TE and TM modes. While effectively guiding TE‐ and TM‐polarized light, the proposed OPA on this platform faces the challenge of overcoming the intrinsically high ...
