Fundamentals of Micro-Optics

Abstract

From optical fundamentals to advanced applications, this comprehensive guide to micro-optics covers all the key areas for those who need an in-depth introduction to micro-optic devices, technologies, and applications. Topics covered range from basic optics, optical materials, refraction, and diffraction, to micro-mirrors, micro-lenses, diffractive optics, optoelectronics, and fabrication. Advanced topics, such as tunable and nano-optics, are also discussed. Real-world case studies and numerous worked examples are provided throughout, making complex concepts easier to follow, whilst an extensive bibliography provides a valuable resource for further study. With exercises provided at the end of each chapter to aid and test understanding, this is an ideal textbook for graduate and advanced undergraduate students taking courses in optics, photonics, micro-optics, microsystems, and MEMs. It is also a useful self-study guide for research engineers working on optics development.

Physical Properties and Characteristics of III-V Lasers on Silicon

“…The lasers must be compatible with CMOS processes in order to be integrated in a commercially viable manner with Si-micro-electronics. It is well known that bulk Si is not a suitable laser active region due to its indirect bandgap meaning that gain is intrinsically weak and nonradiative processes are problematic [8]. This has led to many and varied and often complicated techniques to develop a laser on Si.…”

Micro-optics: a micro-tutorial

“…As we have stressed repeatedly above, one of the key distinguishing features of micro-optics is how the components are fabricated: rather than classic grinding, polishing and machining techniques, micro-optics tends to use the technologies of microfabrication, as established for microelectronics and Table 2 is based on [3] (p. 95); data from [11] (Table 4.1), [12] (Table 6.1) and [13] . using variations on molding techniques [14] .…”

“…The small sizes of micro-optical components allow the use of numerous physical effects for tuning the optical characteristics of a device which are not applicable on larger-size scales; in particular, the use of liquids and deformable materials has led to a broad spectrum of inherently tunable micro-optical components ( [3] , Chapter 12; [47] ).…”

“…Using liquids both as optical media and as actuation means for components has also led to a variety of creative components and systems ( [3] , Chapter 13; [16,54] ). Among the types of devices demonstrated are fl uidic microlenses [53] ; fl uidic microscopes [55] ; fl uidic attenuators and irises [56,57] ; fl uidic microprisms [58] ; and even fl uidic lasers [59] .…”

Highly Efficient Trans-Reflective Color Filters Incorporating TiO2-MgF2Multilayer Stacks

“…MgF2, which was widely used for optical coatings in light of its prominent properties in terms of a wide transmission window spanning from UV up to mid-infrared (200 nm ~ 7 μm), high robustness against humidity and mechanical abrasion, is perceived to be an outstanding candidate as a low-index layer associated with BSs with a high index contrast, leading to enhanced reflectivity with a minimal number of pairs [15]. Driven by those advantages, numerous works on TiO2-MgF2 multilayer stacks have been reported for different applications such as bandpass filtering and anti-reflection and high-reflection coatings [16][17][18][19]. However, the application of the material combination towards the realization of structural color filters has rarely been discussed.…”
