Feedforward-based free-space optical communication
Applied Optics, 2021We propose to use 1-bit feedforward information at the free-space optical (FSO) receiver to improve its error performance. We concentrate upon M -ary pulse amplitude modulation (PAM) signaling and design an error-optimal PAM constellation for providing efficient 1-bit feedforward information to the receiver.

Free Space Optics for 5G and Beyond
2021 6th International Conference for Convergence in Technology (I2CT), 2021For developing countries it is essential to have cost effective, large band width, high data rate network. This can be achieved by Optical wireless channel or free space optics (FSO), which is a new technology in an optical communication system.

SPIE Proceedings, 1990
Free-space optical components and systems can be fabricated using planar techniques such as pattern generation using an electron-beam writer, photolithography, reactive ion etching and thin film deposition. This allows to integrate several optical components such as lenses and beamsplitters on one side of a single substrate [1]; see Fig. 1.
