Electrical and Computer Engineering: RF, Microwaves, and Optoelectronics Focus Area

RF, microwave and optoelectronics deals with circuits, devices and systems operating at high frequencies. RF/Microwave components are a key part of both wireless and wireline communication and radar systems. Knowledge of high-frequency circuit/device design is critical for applications such as cellular phones, WLAN, high-speed Ethernet and collision-avoidance radar. Optoelectronics is the study and design of electronic devices that interact with light. Examples of such devices include the semiconductor lasers used in CD players and fiber optic communications, lasers used in medicine and micromachining, and the image sensors found in digital cameras. Students in this focus area will learn the basics of semiconductor electronic devices as well as optics, lasers, guided-wave optics, and active/passive high-frequency integrated circuit design. Oregon State faculty work with graduate and undergraduate students to perform advanced research in this area.

Career opportunities include circuit design companies making cellular/WLAN chipsets, large consumer electronics companies (DVD players, digital cameras, digital projects, displays, etc.), telecom fiber companies, and many small companies specializing in optical devices and wireless systems for diverse applications in civilian and military technology.
