Indicators (SPIs)

SPIs are a subset of the abilities a student will be able to demonstrate upon successfully completing the course.

Outcome 1 (Students will demonstrate expertise in a subfield of study chosen from the fields of electrical engineering or computer engineering):
1.	Explain the fundamental concepts behind waveguiding in integrated photonic waveguides and the properties of the resulting guided modes (e.g., cut-off, group velocity, dispersion)
2.	Demonstrate expertise in the analysis and design of integrated photonic waveguides and calculating their important properties using Maxwell?s equations and boundary conditions

Outcome 2 (Students will demonstrate the ability to identify and formulate advanced problems and apply knowledge of mathematics and science to solve those problems):
1.	Explain different types of integrated photonic resonators and the properties of their resonant modes (resonance wavelength, mode volume, quality factor, and free spectral range) 
2.	Demonstrate expertise in the analysis and design of integrated photonic resonators in different materials and calculating their important properties using Maxwell?s equations and boundary conditions

Outcome 3 (Students will demonstrate the ability to utilize current knowledge, technology, or techniques within their chosen subfield):
1.	Explain the mechanisms for coupling different integrated photonic building blocks (i.e., waveguides and resonators) and the analysis and design of such coupled structures to form functional passive devices
2.	Explain different tuning mechanisms (e.g., electro-optic effect, free-carrier plasma-dispersion effect, thermo-optic effect, etc.) and their application for designing active integrated photonic devices, especially modulators, switches, phase shifters, and delay lines.
