Available in PDF, EPUB and Kindle. Book excerpt: Liquid Crystal on Silicon (LCoS) has become one of the most widespread technologies for spatial light modulation in optics and photonics applications. These reflective microdisplays are composed of a high-performance silicon complementary metal oxide semiconductor (CMOS) backplane, which controls the light-modulating properties of the liquid crystal layer. State-of-the-art LCoS microdisplays may exhibit a very small pixel pitch (below 4 μm), a very large number of pixels (resolutions larger than 4K), and high fill factors (larger than 90%). They modulate illumination sources covering the UV, visible, and far IR. LCoS are used not only as displays but also as polarization, amplitude, and phase-only spatial light modulators, where they achieve full phase modulation. Due to their excellent modulating properties and high degree of flexibility, they are found in all sorts of spatial light modulation applications, such as in LCOS-based display systems for augmented and virtual reality, true holographic displays, digital holography, diffractive optical elements, superresolution optical systems, beam-steering devices, holographic optical traps, and quantum optical computing. In order to fulfil the requirements in this extensive range of applications, specific models and characterization techniques are proposed. These devices may exhibit a number of degradation effects such as interpixel cross-talk and fringing field, and time flicker, which may also depend on the analog or digital backplane of the corresponding LCoS device. The use of appropriate characterization and compensation techniques is then necessary.

Available in PDF, EPUB and Kindle. Book excerpt: Spatial light modulation is a technology with a demonstrated wide range of applications, especially in optical systems. Among the various spatial light modulator (SLM) technologies, e.g., liquid crystal (LC), magneto-optic, deformable mirror, multiple quantum well, and acoustic-optic Bragg cells, the ones based on liquid crystal on silicon (LCoS) have been gaining importance and relevance in a plethora of optical contexts, namely, in telecom, metrology, optical storage, and microdisplays. Their implementation in telecom has enabled the development of high-capacity optical components in system functionalities as multiplexing/demultiplexing, switching and optical signal processing. This technology combines the unique light-modulating properties of LC with the high-performance silicon complementary metal oxide semiconductor properties. Different types of modulation, i.e., phase, amplitude or combination of the two, can be achieved. In this book chapter, we address the most relevant applications of phase-only LCoS SLM for optical telecom purposes and the employment of SLM technology in photonic integrated circuits (PICs) (e.g., field-programmable silicon photonic (SiP) circuits and integrated SLM application to create versatile reconfigurable elements). Furthermore, a new SLM-based flexible coupling platform with applications in spatial division multiplexing (SDM) systems (e.g., to efficiently excite different cores in MCF) and characterization/testing of photonic integrated processors will be described.

This book was released on 2020-10-05 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: This brief monograph provides reports on liquid crystal materials used for specific devices designed for industrial applications. The authors of each chapter present insights on the design and technical aspects of the manufacturing of advanced liquid crystal light modulators reflecting their experience in advanced liquid crystal materials science. Chapters in the book first introduce readers to the chemistry and basic materials science of liquid crystal light modulators with information important for practical situations such as custom manufacturing and material quality assessment (including the determination of Frank elastic constants). Subsequent chapters cover a selection of interesting projects where liquid crystal light modulators are applied, such as: a highly transparent, laser damage resistant liquid crystal phase modulators for space-borne laser rangefinders; a dynamic optical filter designed for visualization of air pollution; a high contrast, fast operating, outdoor light shutter for the eye protection of welders. Readers will gain an awareness of the peculiarities of the liquid crystalline matter, along with the complexity of the design and fabrication of active optical elements, as the information provided in this volume presents detailed practical results of the liquid crystal technology projects.
