The generation, transport, manipulation, detection, and use of light are at the heart of photonics. Photonics is a growing career field with a projected growth rate of 10% to 20% over the next decade. Photonics technicians and engineers must master new concepts, learn new techniques, and develop new skills derived from a highly developed understanding of the nature of light…
Holography is a much broader field than most people have perceived. Recording and displaying truly three-dimensional images are only small parts of it. Holographic optical elements (HOE) can perform the functions of mirrors, lenses, gratings, or combinations of them, and they are used in myriad technical devices. Holographic interferometry measures microscopic displacement on the surface of an object and small…
This module addresses various non-laser light sources, such as incandescent lamps, fluorescent discharge lamps, high-intensity discharge lamps, flashlamps, arc lamps, and LEDs. It also discusses laser safety in detail, including the human eye, laser hazards, laser safety controls, maximum permissible exposure, laser safety glasses, and laser accidents. The laboratory experience at the end of the module will enhance the learner's…
This module covers the first of two main divisions of basic optics-geometrical (ray) optics. Module 1.4 covers physical (wave) optics. Geometrical optics will help you understand the basics of light reflection and refraction and the use of simple optical elements, such as mirrors, prisms, lenses, and fibers. Physical optics will help you understand the phenomena of light wave interference, diffraction,…
In this module, we concentrate on light waves and away from light rays, as covered in Module 1.3. In so doing, we move from a concern over the propagation of light energy along straight-line segments to one that includes the spreading of light energy-a fundamental behavior of all wave motion. With wave optics-commonly referred to as physical optics-we are able…
This module is an in-depth explanation of lasers as they apply to the larger field of optics and photonics. Anyone going through this module should have already completed Modules 1.1-1.4 and have a good working knowledge of algebra, exponents, and logarithms. Lasers are devices that amplify or increase the intensity of light to produce a highly directional, high-intensity beam that…
In this module, we describe some common optical detectors and their important characteristics. We do not cover the entire field of light detection, which is very broad. Instead, we emphasize those detectors that are most commonly encountered in photonics applications. The two main types of optical detectors are photon detectors and thermal detectors. Photon detectors produce one electron for each…
This module is an introduction to the basics of fiber optics, discussing especially the characteristics of optical fibers with regards to the fabrication of low-loss optical fibers and the room-temperature operation of semiconductor lasers in 1970. Within a brief span of 30 years, we are now in the fifth generation of optical fiber communication systems. Recent developments in optical amplifiers…
Fiber optics is a major building block in the telecommunication infrastructure. Its high bandwidth capabilities and low attenuation characteristics make it ideal for gigabit transmission and beyond. In this module, you will be introduced to the building blocks that make up a fiber-optic communication system. You will learn about the different types of fibers (and their applications), light sources and…
Electronic and electro-optic devices are frequently used to display images obtained from the computer processing of data. Images, or digital pictures, are generally two-dimensional data structures that convey spatial information to the viewer. Images are collected through various means, from digital cameras to laser radar scanning systems. Once stored in a computer, these images can be manipulated mathematically to accomplish…
Wide Bandgap Semiconductors GaN, SiC module was created to introduce this emerging field in the engineering technology and related associate level curriculum.
