We experimentally validate the rapid adiabatic coupling (RAC) concept and demonstrate 50±1.4% (3±0.12 dB) power splitting over a record 145 nm bandwidth from either port of a 31µm-long, 2×2 coupler, the widest ±1.4%-bandwidth by a factor of 4.
We demonstrate a 75 µm-long rapid adiabatic coupler (RAC) with an average insertion loss <0.025 dB/coupler and an average power splitting ratio of 50±1.09% over 40 nm bandwidth and 68 reticles across a 300 mm 45 nm SOI CMOS wafer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
