CAPT 3040: Introduction to Photonic Systems Engineering Instructor: Tom Mahony Course Description: Photonic Systems engineers are responsible for conceiving, specifying and developing products that use light as a cardinal factor in the product design. Photonic systems are usually the products of optical, mechanical, and electrical engineering as a minimum. Quite often, control systems, thermal management and signal and image processing are also involved. The photonic engineer can not be an expert in each of these disciplines but it is essential that he have the ability to communicate effectively with each discipline. This course lays down a foundation of principles upon which photonic systems are based and developed. A photonic system either creates light, manipulates light, or detects light, or somehow combines all three. A generic photonic system will be described as the flow of a signal input to a delivered output with supporting subsystems effecting that flow. Supporting subsystems may be either fundamental to signal flow or underlying in controlling a system operating environment such as temperature or vibrational stability. The concept of block transfer functions and additive sources of noise will be introduced. In that vein, the following topics will be discussed: What is System Engineering? The Common Language of Optical, Electrical and Mechanical Engineering Signal to noise as the fundamental system figure of merit. Probability of Detection, False Alarm rates, Bit Error Rates as a measure of system performance Noise Equivalent Power, Noise Equivalent Temperature, Noise Equivalent Range The Nature of a Photonic Signal The six dimensions of a photonic signal: Magnitude, Space (x,y), Time, Wavelength and Polarization. Common light sources and their characteristics including Blackbodies, Lamps and Lasers The collection of light from common sources including point, extended and directed sources Interaction of light with the environment and optical materials Sources of Noise Background induced Temporal and Spatial Sources of noise in the collection process Device induced sources of spatial and temporal noise including shot noise and Johnson noise Pointing Stability and Vibration induced noise sources Optimizing Signal to Noise Ratio Spectral (wavelength), spatial (pixel) and temporal (electronic) matched filters Proper Selection of Detector material Frequency Shifting the signal for enhanced signal to noise System Architecture Issues Nyquist Sampling Theory for spatial and temporal systems Effects of quantization Environmental Degradation of System Performance Temperature Background Off-Axis Sources Common causes of system degradation Finally, a philosophical approach to technical risk management will be discussed that will guide the system engineer through the complex jungle of system trade-offs in a timely and cost effective manner. Who Should Attend: This course is targeted at engineers and scientists of all disciplines who find themselves emerging as a "photonic system engineer". Attendees should come into the class with a basic engineering background with prior exposure to the concepts of frequency response and time variable signals. Exposure to the concepts of Fourier Transform and response convolution principles is highly beneficial. About the Instructor Tom Mahony has been active in the Photonics Industry for nearly 30 years. He was a Senior Member of the Technical Staff at Hughes Aircraft working on space borne infrared surveillance systems for 10 years. Subsequently, he worked in a similar capacity at Ball Aerospace in the early 1980's as the Technical Director of the Optical Airborne Measurements program. In 1984, he co-founded Boulder Electro-Optics, which was acquired by Melles Griot in 1986, and which now operates as the Melles Grot Electro-Optics Division located in Boulder. At Melles Griot, Tom was a Corporate Vice-President, and General Manager of the Electro Optics Division, Tom currently serves as the Executive Director of the CAPT Center.
