Example: PLC Chip-to-Fiber Alignment
Mechanical Setup:Mount the fiber array and chip on the platform using fixtures. Align each component’s plane and height, ensuring coplanarity and initial positioning accuracy. Fine-tune all axes to minimize angular and positional offsets for optimal coupling.
Initial Optical Alignment:Perform coarse optical alignment along X and Y axes. Use live imaging (overlay of oblique and coaxial views) to assess misalignment. Adjust until the input/output ports of the fiber and chip are well aligned and focused. Light coupling signal appears on the CCD once aligned.
Visual Monitoring:With low-power light coupled into the device, monitor the near-field output (typ. 100–200 μm distance) to evaluate alignment. Adjust rotational angle and height as needed. Use image-based alignment and feedback to iteratively optimize coupling. Fine adjustments are made in ≤10 μm steps.
Signal Optimization:Inject signal light and monitor output power to perform fine tuning. Ensure coupling loss is minimized. Complete alignment of each channel one by one.
UV Curing:Once alignment is complete, apply UV curing to fix the device.
Device Removal:Release the fixture, remove the bonded device, and proceed to testing.
