Three-Port Polarization Maintaining Fiber Circulator
The three-port polarization maintaining fiber circulator is a multi-port non-reciprocal optical device. It allows signals to transmit in one direction. When signals enter Port 1, they exit from Port 2, and signals entering Port 2 exit from Port 3. Similarly, signals entering Port 3 exit from Port 1. The device features low insertion loss and high isolation, making it suitable for various applications.

Semiconductor laser diodes are essential light sources for industrial sensing, LiDAR and laser printing. Many engineers waste time picking mismatched models. We summarize 4 simple selection standards, plus a mature industrial product: HGLD-790TO5.6-ZSP-10mW from HAUCORE.
Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
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.
