Leakage Current Sensor

VCSEL, short for Vertical Cavity Surface Emitting Laser, is a widely used semiconductor laser component in modern optoelectronics. Unlike traditional edge-emitting lasers, VCSEL emits laser light vertically from its chip surface. Thanks to its low power consumption, stable beam quality, low cost, and easy integration, it has become the core light source for 3D sensing, wearable devices, and high-speed optical communication.

Founded in Beijing in 2011, Beijing FJR Opto-electronic Technology Co., Ltd. specializes in R&D, manufacturing and sales of infrared thermal imaging equipment and complete optoelectronic systems.

In photonics and laser technology, devices that manipulate optical signals via the electro-optic effect form the backbone of precision optical systems. Electro-optic phase modulators and electro-optic deflectors are two prominent examples of this device category. As a critical hardware solution for high-speed, high-accuracy laser beam direction control, electro-optic deflectors are widely deployed across industrial and research settings. Below is a detailed overview of their core structure, key performance drivers, and primary use cases.
