A Niobate Lithium (LiNbO3) photonic integrated chip (PIC) was manufactured to optically combine via balancing and rephasing of 8 disturbed signals collected and demultiplexed by an MPLC. Cascaded on-chip Mach-Zehnders interferometers containing controllable phase shifters allow combining of optical inputs two at a time. Optical leaks are used as feedback loops. After 3 stages, all signals are coherently combined into a main output. We present efficiency, bandwidth, and compatibility with telecom operation of the PIC recombination.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\" style=\"margin-top:0;margin-bottom:0\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/www.spiedigitallibrary.org\/conference-proceedings-of-spie\/PC11993\/PC1199303\/On-chip-coherent-phase-and-intensity-control-for-atmospheric-turbulence\/10.1117\/12.2611380.short#_=_\" target=\"_blank\" rel=\"noreferrer noopener\">More information<\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>SPIE LASE 2022<\/p>\n","protected":false},"author":2,"parent":0,"template":"","categorie-publication":[99],"class_list":["post-5693","publication","type-publication","status-publish","hentry","categorie-publication-aerospatial-et-defense"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 -
