Optical Modulator Parameters
Depending on the parameter of a light beam which is manipulated, modulators may be categorized into amplitude modulators, phase modulators, polarization modulators, etc.

Optical switch of electro-optic modulator
Suitable electronic circuits can switch such large voltages within a few nanoseconds, allowing the use of EOMs as fast optical switches. Liquid-crystal devices are electro–optical phase modulators if no polarizers are used. Phase modulation (PM) is a modulation pattern that encodes information as variations in the instantaneous phase of a carrier wave.

Door-to-door optical modulator QSFP-DD
QSFP-DD (Quad Small Form Factor Pluggable Double Density) is an evolution of the QSFP family, extending its lane capacity from 4 to 8 high-speed electrical lanes. Each lane supports up to 50G PAM4 signaling, delivering an aggregate throughput of 400G — or even 800G in advanced PAM4. Cisco ® QSFP-DD and OSFP 800G ZR/ZR+ coherent optics modules enable 800G traffic over.

SLM optical modulator
A spatial light modulator (SLM) is a device that can control the intensity, phase, or polarization of light in a spatially varying manner. SLMs are primarily marketed for image projection, displays devices, and maskless lithography. (MIIPS) is a technique based on the computer-controlled phase scan of a linear-array spatial light modulator.
