We demonstrate an optical 64QAM modulator operating at 60 Gb/s (with single polarization).Asymmetric couplers and an array of 12 high-speed phase modulators are integrated with a hybrid configuration ...
Novel guided-wave electro-optic (EO) single side-band (SSB) modulators by using periodically polarization-reversed structures are proposed and demonstrated. Adopting the polarization-reversal schemes ...
This paper describes the recent advances made in silicon optical modulators employing the free carrier dispersion effect, specifically those governed by majority carrier dynamics. The design, fabricat...
We discuss a new method to design traveling-wave electrooptic modulators with controlled frequency responses using nonperiodically polarization-reversed structure. Using our method, the frequency resp...
We demonstrate a direct measurement of the complex ultra-fast temporal response of optical modulators (with a bandwidth ~ 40GHz in the reported example) enabling real-time characterization of instant...
