Electro-optic Modulator Shielding for Crosstalk Reduction

The patent introduces electromagnetic shielding structures (metal shielding plates or conductive layers) as intermediary elements between adjacent channels. These shielding structures act as mediators that block electromagnetic field radiation from one channel from reaching adjacent channels, thereby eliminating crosstalk while maintaining high channel integration density. The shielding structures are positioned strategically within the waveguide structure to provide effective isolation.

The patent applies preliminary anti-action by pre-installing electromagnetic shielding structures during the manufacturing process to prevent crosstalk before it occurs. The shielding structures are integrated into the waveguide fabrication process, ensuring that electromagnetic radiation is blocked from the outset rather than attempting to correct crosstalk after it has affected signal transmission.

The patent introduces electromagnetic shielding structures as intermediary elements that block electromagnetic radiation from the traveling wave electrodes. These shielding structures (metal plates or conductive layers) are positioned adjacent to the electrode structures and serve as mediators that prevent harmful electromagnetic radiation from propagating outward while allowing the high-speed modulation function to continue operating at full bandwidth.

The patent converts the harmful electromagnetic radiation into a beneficial configuration by using the same electrode structures that generate radiation also as part of the shielding system. The electrode structures are designed to work in conjunction with the shielding, where the radiation pattern is controlled and directed, and the shielding structures are positioned to leverage the existing electromagnetic field distribution to achieve effective blocking with minimal impact on modulation performance.
