[Legacy Report] Tutorial: Introduction to Linear Photonics (Sending RF/Microwave Over Fiber)

---

Abstract: This tutorial talk will begin with an overview of analog microwave photonic link technology with an emphasis on advanced techniques for enhancing system linearity. The distinctions between analog (linear) and digital photonics will be included. A discussion of direct and external modulation techniques, receivers and link performance will be presented, along with typical performance characteristics of readily-available equipment. The requirements of key systems where fiber optics is either actively employed, or remains out of reach for technical or cost considerations will be reviewed. The use of both pre and post distortion linearization and feed forward techniques to improve system performance will be included. The contrast in performance versus requirements will be used to highlight the growth opportunities for next-generation optical links. We will conclude with a review of the activities and techniques for improving the cost and technical capabilities of microwave fiber optic links, and how the growth opportunities will be addressed.
