Travelling Wave Electrode on Electroabsorption Modulator Based on Asymmetric Intra-step-barrier Coupled Double Strained Quantum Wells Active Layer
نویسنده
چکیده
In this paper, a travelling wave electroabsorption modulators (TWEAMs) based on asymmetric intra-stepbarrier coupled double strained quantum wells (AICD-SQW) active layer is designed and analyzed at 1.55 μm for the first time. The AICD-SQW structure has advantages such as very low insertion loss, zero chirp, large Stark shift and high extinction ratio in comparison with the intra-step quantum well (IQW) structure. For this purpose, the influence of the electrode width and ground metal separation on their transmission line microwave properties (microwave index, microwave loss, and characteristic impedance) and modulation bandwidth are analyzed.

We demonstrate an electroabsorption modulator on a silicon substrate based on the quantum confined Stark effect in strained germanium quantum wells with silicon-germanium barriers. The peak contrast ratio is 7.3 dB at 1457 nm for a 10 V swing, and exceeds 3 dB from 1441 nm to 1461 nm. The novel side-entry structure employs an asymmetric Fabry-Perot resonator at oblique incidence. Unlike wavegui...

An electroabsorption modulator using a side-entry architecture achieved a contrast ratio exceeding 3 dB over a 3.5 nm range in the C-band, using a voltage swing of 1 V and operating at 1008C. Modulation was due to the quantum-confined Stark effect from ten Ge/SiGe quantum wells epitaxially grown on silicon-on-insulator (SOI) wafers. The device exploits an asymmetric Fabry-Perot resonator formed...
