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.

Optical Barrier Modulator
The treatment of glioblastoma has limited clinical progress over the past decade, partly due to the lack of effective drug delivery strategies across the blood-brain-tumor barrier.
