Abstract

A Fourier transform spectrometer (FTS) chip based on silicon-polymer hybrid waveguide is proposed. The silicon-polymer hybrid waveguide consists of a silicon slot waveguide filled with an electro-optic (EO) polymer. The EO coefficient of employed EO polymer can be as large as 359 pm/V, resulting in a π-voltage-length product of less than 0.1 V·mm for our designed FTS chip which features a high resolution of 2.2 nm with a compact size of less than 0.5 mm².
