A project report on the design, optimization, and analysis of single-mode fiber coupling using corning smf-28e fiber and suss microoptics fc-q-250 microlens arrays. The report includes the initial design, paraxial gaussian beam data analysis, physical optics propagation, and the application of coatings to improve efficiencies. The project aims to minimize phase errors and maximize coupling efficiency.

We can start our initial design, which couples two pieces of Corning SMF-28e Fiber using SUSS MicroOptics FC-Q-250 microlens arrays. After we set our system corresponds to the manufacturer's' data, our lens data and layout will be like bellow: After this initial design, we shoul use The Paraxial Gaussian Beam Data analysis, it is the simplest of the analytic tools we will use to characterize the fiber coupler.
Optimizing the fiber/lens distance gives a value of 0.117 mm for the fiber/lens distance, and the following Gaussian beam data.
Our phase/x graph will be:
After we apply coating, our efficiencies will be:
