Passive Photonic Integrated Circuit Components
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Passive photonic integrated circuit (PIC) components form the backbone of many optical systems, enabling the manipulation and routing of light with high precision and efficiency. This category encompasses a diverse array of elements, each designed to perform specific functions without the need for external power. These components exhibit a wide range of functionalities including light coupling, splitting, filtering, and polarization control.
