Optical Fiber Waveguide Alignment System
Fibermart Fiber Waveguide Alignment Stages are Dual 6-axis positioning motorized stages, provides PC workflow software controlling, continuous motion with micron or sub-micron resolution and long-term stability, working for Fiber to Chip coupling, Fiber Array Unit FAU to Chip coupling, or Fiber Array to Waveguide coupling, which are the mechanical properties required to couple light from optical fibers to waveguides or other fiber optic components like PIC or Chip Packages.
Fibermart offers several fiber waveguide alignment systems including Manual Align System, SemiAuto Align-Systems and 12-axis Full Automated Align Systems for fiber optic workshop prodcution line or research labs. With Core Motion Part, Mechanical Fixtures(with touch sensor), Vision System, Workflow Process Control Software, Power Meter, Light Source, UV Curing System, Epoxy Dispensor, Unti-Vibration Table etc, our Fiber to Waveguide Align systems use thumbscrews for manual positioning with micron resolution or use PC workflow process software controlled by stepper motor to finish the fiber/FA to waveguides coupling. For nanometer positioning, our full auto stages are available with differential micrometer or stepper motor actuators, also with either open-closed loopback coupling for auto-alignment.
IntroductionFibermart's Fiber Waveguide Alignment Stages represent the pinnacle of precision opto-mechanical systems, engineered for the exacting task of coupling light between optical fibers and photonic integrated circuits (PICs) or waveguides. These sophisticated systems, ranging from manual configurations to fully automated 12-axis platforms, provide the sub-micron resolution and long-term stability essential for high-efficiency light coupling in production and research. Featuring PC-controlled workflow software, integrated vision systems, and vibration-dampening technology, they are the definitive solution for achieving optimal alignment in Fiber-to-Chip, Fiber Array Unit (FAU)-to-Chip, and other critical photonic packaging applications.  Features
● Multi-Axis Precision Positioning with manual, motorized, or piezo-driven stages offering up to 12 axes of control for complex, multi-degree-of-freedom alignment. Principles
The core principle of fiber waveguide alignment is to achieve maximum optical power transfer by positioning the core of an optical fiber in perfect spatial overlap with the mode field of a waveguide or optical chip. This requires movement with micron and sub-micron precision across multiple linear and rotational axes (X, Y, Z, θx, θy, θz) to correct for all possible misalignments.
Manual and semi-automated systems achieve this through precision thumbscrews or micrometers, with alignment visually monitored via cameras and optimized by observing a connected optical power meter. The workflow software then guides the operator or controls motorized actuators to find the peak power position. Fully automated systems implement a closed-loop feedback principle. The software directly controls motorized or piezo stages, continuously adjusting the position while monitoring the real-time power meter reading. It executes algorithms to automatically hunt for and lock onto the position of maximum coupled optical power, ensuring consistent, hands-off alignment with nanometer-level precision and long-term stability.
