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…

Electro-Optic Modulator

This lesson shows how to make a 3D simulation in a material modified by the linear electro-optic effect (Pockels Effect). The waveguide design of Reference [1] is shown in Figure 1 below. In this lesson, this waveguide is created, a potential is applied to the electrodes, and the results are compared to Reference [1]. Figure…

Integrated Optical Circuit Simulation Using OptiBPM and OptiSystem – Scattering Data Export

Scattering data is a new simulation feature in OptiBPM. OptiBPM uses scattering data when a small part of a larger photonic circuit is isolated for characterization using BPM. This smaller part has waveguides entering on the left side and exiting on the right side. The N inputs and the M outputs are assumed to have…
