Summary

1 / 6

Past student reviews · Srdjan Milicic

The primary burden came from writing 5-8 page individual lab reports after each session. Students noted these reports required detailed sections and took approximately five hours to complete.

What you’ll be able to do

  • Describe the relationship between the light emission/detection properties of semiconductors, and the operation of optoelectronic devices, such as light emitting diodes (LEDs), lasers and optical fibers

  • Perform optical characterization measurements using laboratory instruments

Past student reviews · Srdjan Milicic

Srdjan Milicic required 5-8 page individual lab reports after each session. Students described this as excessive work for a 1-credit course, with one estimating reports took five hours and another suggesting the workload matched a 3-4 credit class.

Reviewers reported that Milicic deducted points for minor report errors and was lecture-heavy without providing notes or recordings. One student noted homework covered only 30% of exam material.
