As technology and innovation advances so does the amount of information processing required, leading to a need for faster and more reliable ways for information transfer. Optical fibers are currently set to be industry standard for large bandwidth data transfers and processing but they require precise alignment and attachment. There are two primary methods for alignment and attachment for optical fiber, mainly active alignment using a feedback loop system and passive alignment with the use of mechanical structure guides. Passive alignment and attachment methods are being further studied for high volume manufacturing due to faster alignment time and cheaper cost to upscale but at the expense of optical power loss. However, with newly formulated optical adhesives the loss of optical power can be minimized. Preliminary work was done to evaluate suitable adhesives samples and designed a testing method to be used for the baseline response for the selected adhesives. This project was based on evaluating different types of fiber optic adhesive samples from the same provider and tested how accurate the xyz positions are pre & post cured. The power lost due to misalignment caused by adhesive optical and mechanical characteristics, was measured with a power meter and a light source and compared to the misalignment under an optical microscope. The right choice for selecting the right adhesive for optical fiber passive alignment and attachment can be as efficient as possible based on the baseline response data.
