A Design of All-Optical Integrated Linearized Modulator Based on Asymmetric Mach-Zehnder Modulator
We proposed an all-optical linearized modulator model suitable for an integration platform. The linearized modulator is formed by an asymmetric Mach–Zehnder modulator and a carrier-separated waveguide. We focus on the suppression of both intermodulation distortion (IMD3) and second-order harmonic di...

| description | We proposed an all-optical linearized modulator model suitable for an integration platform. The linearized modulator is formed by an asymmetric Mach–Zehnder modulator and a carrier-separated waveguide. We focus on the suppression of both intermodulation distortion (IMD3) and second-order harmonic distortions (SHD). As a result, the third-order nonlinear terms of IMD3 and second-order nonlinear terms of SHD are entirely suppressed, leading to a spurious free dynamic range of IMD3 (SFDR<sub>IMD3</sub>) improvement of ~14 dB and SFDR<sub>SHD</sub> improvement of ~3 dB compared with a standard MZM model. The influence of large RF input signals, losses, and fabrication deviations are also discussed to prove the feasibility of the model. |
