Optical Engineering Overview

Principles

Definition

Optical engineering is an interdisciplinary field that applies the principles of physics, particularly optics, and engineering methodologies to the design, development, and implementation of light-based systems, devices, and components. It investigates the behavior of light and its interaction with matter for practical applications, bridging fundamental optical science with technological innovation across diverse industries.

Multiplexed Optical Information era

M. G. Moharam [1] was affiliated with Georgia Institute of Technology [3] and the University of Virginia [4] during this era. His key contribution in this era was the stable implementation of the rigorous coupled-wave analysis for surface-relief gratings—the enhanced transmittance matrix approach described in the 1995 paper [7], which improved the reliability of modeling diffractive structures and supported high-fidelity three-dimensional optical encoding. R. R. Alfano [2] was affiliated with Cornell University [5] and New York Medical College [6] during this era. His Ballistic 2-D Imaging Through Scattering Walls Using an Ultrafast Optical Kerr Gate [8], published in 1991, exemplified ultrafast temporal gating that enabled imaging through turbid media and informed readout strategies for multiplexed information systems.

Computational Sensing and Metrology era

In the Computational Sensing and Metrology era of 2000–2013, canonical figures such as James G. Fujimoto, Xingde Li, Zhongping Chen, Stephen A. Boppart, and Aydogan Ozcan epitomized the field. Fujimoto and Li drove the rapid evolution of optical coherence tomography, advancing frequency-domain and swept-source implementations that enabled high-speed, high-resolution in vivo imaging. Chen and Boppart expanded multimodal, computer-assisted sensing with polarization-sensitive and spectral-domain OCT, tissue characterization, and hardware–software co-design for reliable diagnostic workflows. Ozcan exemplified computational sensing and lensless optics, delivering quantification through algorithmic reconstruction, smartphone-enabled metrology, and cross-disciplinary toolchains that aligned measurement standards with practical biomedical applications.

Integrated Metasurface Optics era

Federico Capasso [1], affiliated with Harvard University [3] and Duke University [4], was a pivotal figure in integrated metasurface optics during the 2014-2023 era. His contributions include the broadband achromatic metalens for focusing and imaging in the visible [6] and polarization-insensitive metalenses at visible wavelengths [7], which advanced broadband and polarization-robust flat optics essential for ultrathin imaging systems. Wei Ting Chen [2], affiliated with Harvard University [3] and Xiamen University [5], contributed to polarization-insensitive metalenses in the visible. This work by Wei Ting Chen [2] on polarization-insensitive metalenses at visible wavelengths [7] exemplifies a core capability for polarization-robust, compact flat optics in integrated metasurface imaging pipelines.
