How It Works

The modulator tube shell provides mechanical support, electrical connections, optical interfaces, and environmental protection for the optical modulator chip. For commonly used lithium niobate (LiNbO₃) optical modulators, the modulation voltage is applied to the modulator electrodes; through the electro-optic effect, it changes the refractive index of the waveguide, thereby changing the phase or intensity of the optical signal passing through to achieve optical signal modulation.

Optical signals enter the modulator through an input fiber or waveguide, and after modulation exit through an output fiber or waveguide. The tube shell must ensure precise alignment and long-term stability between the input/output fibers and the modulator waveguide. High-frequency modulation signals are input to the modulator electrodes through high-frequency pins; the pin design and internal structure of the tube shell must support high-quality transmission of high-frequency signals.
