An electro-optic modulator (EOM) is a device that controls the power, phase or polarization of an optical signal through an electrical signal. Its core principle is based on the linear electro-optic effect (Pockels effect). This effect manifests itself in that the applied electric field is proportional to the refractive index change of the nonlinear crystal, thereby achieving effective control of the optical signal.

In cutting-edge optoelectronic fields such as optical communication, lidar, and photonic integration, semiconductor optical amplifiers (SOAs) serve as core devices for optical signal enhancement. Boasting advantages of small size, low cost, easy integration, and fast response speed, they are gradually replacing traditional optical amplification solutions and have become a key component supporting the development of high-speed optical networks and high-power optical systems. This article will analyze the working principles and full-scenario applications of SOAs in detail, and focus on discussing the technical characteristics, design challenges, and application value of high-power SOAs, helping to fully understand the core advantages of this "optical signal booster."

A pump laser is a laser used to provide an excitation light source for a fiber laser or fiber amplifier. The emission wavelength of a 980nm pump laser is approximately 980 nanometers (nm).

Fluorescence imaging has been widely used in biomedical imaging and clinical intraoperative navigation. When fluorescence propagates in biological media, absorption attenuation and scattering disturbance will cause fluorescence energy loss and signal-to-noise ratio decrease, respectively. Generally speaking, the degree of absorption loss determines whether we can "see", and the number of scattered photons determines whether we can "see clearly". In addition, the autofluorescence of some biomolecules and signal light are collected by the imaging system and eventually become the background of the image. Therefore, for biofluorescence imaging, scientists are trying to find a perfect imaging window with low photon absorption and sufficient light scattering.
