Lesson 9: Create a Chip-to-Fiber Butt Coupler

This lesson describes how to create a chip-to-fiber coupler. You will create a model of a simple spot-size transformer based on lateral tapering, as reported in [1]. Highly efficient chip-to-fiber coupling with large alignment tolerances is important for applications of optoelectronic integrated semiconductor devices. Such coupling requires a low-loss change of the light beam spot…
