Novel electro-absorption modulator with germanium fins evanescently coupled to silicon waveguide
Novel electro-absorption modulator with germanium fins evanescently coupled to silicon waveguide
Electro-Absorption (EA) modulator is a promising candidate for the next generation devices in Si photonics with even lower power consumptions for short-reach optical interconnections. However, its relatively higher insertion loss must be addressed, and the efficient coupling from a Si waveguide to EA modulator is a challenging topic. Here, we propose, for the first time, to use novel Ge fin structures for EA modulators. An array of Ge fins evanescently coupled to a Si waveguide is used for the modulation by the Franz-Keldysh effect (FKE). We have designed this new EA modulator using Ge fins based on simulations.

Abstract
Electro-Absorption (EA) modulator is a promising candidate for the next generation devices in Si photonics with even lower power consumptions for short-reach optical interconnections. However, its relatively higher insertion loss must be addressed, and the efficient coupling from a Si waveguide to EA modulator is a challenging topic. Here, we propose, for the first time, to use novel Ge fin structures for EA modulators. An array of Ge fins evanescently coupled to a Si waveguide is used for the modulation by the Franz-Keldysh effect (FKE). We have designed this new EA modulator using Ge fins based on simulations.
