MIC633 Photonic Sensors for Chemical, Biomedical and Environmental Applications

Instructor: Dr. Clara Dimas
Pre-requisites: MIC630 or MSE 509
Next time offered:  to be determined

Brief Description:

The course is focused on the achievement of a clear and rigorous understanding of the fundamental properties, concepts and theories which are of importance in photonic sensors. Photonic sensor designs have been developed and demonstrated to have small footprint, light weight, high resolution, immunity to electromagnetic interference, harsh environment operational capability, "long-reach" access potential, multiplexing capability for certain sensor designs and low cost implementation attributes. Within this dynamic field which includes advances in light sources, fibers, probes, and nano/micro scale fabrication, the course focuses on photonic components and system configurations needed for chemical, biological and environmental sensing applications.

Lecture schedule, by week:

Week 1: Overview of (i) chemical, environmental and biomedical optical sensors and (ii) photonic devices and advances in fabrication of photonic integrated circuits
Week 2: Advances in light sources (lasers, broadband and supercontinuum light sources), detectors in the visible to THz wavelength regime and system integration impact
Week 3-4: Fiber-based and on-chip sensing based on intensity, phase, frequency and other modulation techniques
Week 5: Waveguide theory and evanescent wave sensing (fiber and on-chip configurations)
Week 6-7: Spectroscopy principles (Fourier, Raman, fluorescent, absorption) and on-chip implementations
Week 8: Mid Term Break
Week 9-10: Piezoresistance & Piezoelectric Materials
Week 10: Fiber optics sensor materials and devices (including grating, smart structures, hollow fiber, photonic bandgap fiber, endoscopy)
Week 11: Interferometric (Mach-Zehnder, Michelson, Sagnac) sensing configurations and figures of merit based on fiber and on-chip systems
Week 12: Optical microfluidics
Week 13: Plasmonics and surface plasmon resonators
