Ultrahigh-responsivity waveguide-coupled optical power monitor for Si photonic circuits operating at near-infrared wavelengths

Autor: Takaya Ochiai, Tomohiro Akazawa, Yuto Miyatake, Kei Sumita, Shuhei Ohno, Stéphane Monfray, Frederic Boeuf, Kasidit Toprasertpong, Shinichi Takagi, Mitsuru Takenaka

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-8 (2022)

The authors presented an ultrahigh-responsivity phototransistor with a thin InGaAs film on a silicon waveguide. The effective gating by the silicon waveguide enables 106 A/W responsivity, promising for optical power monitors in Si photonic circuits.
