Optical connections by GRIN lenses

摘要: GRIN optics is an active area of research in optical fiber transmission systems and sensing. In particular, lenses provide on-axis off-axis imaging Fourier transforming, which are great importance these fields. Taking advantage the inherent features lenses, many configurations for connecting fibers, sources, or detectors by have been analyzed coupling sensing purposes [9.1–9.4]. We will study three typical configurations, that is, single-mode fibers coupled corrective elements astigmatic Gaussian beams from laser diodes anamorphic selfoc beam-size controllers light deflectors made tapered lenses. Other devices using also presented.
