Liquid Crystals - Recent Advancements in Fundamental and Device Technologies
Miniaturization and integration are the main trends in modern photonic technology. In this chapter, two kinds of micro-/nano liquid crystal (LC) layer-based tunable optical fiber interferometers are proposed. One fiber interferometer is the optical fiber gratings (LPGs), and the other one is the locally bent microfiber taper (LBMT). The working principles of the devices are theoretically analyzed. The preparation process and the functional properties of the devices are experimentallydoi:10.5772/intechopen.70413 fatcat:wdlsueid7ngldab42qevtfcjza
