Source: Wikipedia Understanding Electro-Optic Modulators An electro-optic modulator (EOM) is a device that can control the power, phase, or polarization of light using an electrical signal. These modulators are based on the electro-optic effect, where the refractive index of a material changes in response to an electric field. Types of Electro-Optic Modulators Phase Modulators: These […]

Source: Wikipedia Understanding Photon Counters Photon counters are photodetectors that are so sensitive that they can detect single photons. This capability allows for the registration of individual photon absorption events rather than measuring optical intensity or power. Photon counters are crucial for experiments in quantum optics where coincidences between multiple detectors need to be recorded.

Source: Wikipedia Understanding Chromatic Aberrations in Optics Understanding Chromatic Aberrations in Optics Introduction to Chromatic Aberrations Chromatic aberrations are optical distortions that often occur in imaging systems. These distortions arise due to the wavelength-dependent refraction at air-glass interfaces in optical lenses. Chromatic aberrations can also be observed in prisms and diffractive optics. However, reflective optics,
