摘要

Low-cost packaging and compact-size of optical fiber based optoelectronic devices and passive components have become vogue of enlargement in telecommunication, sensors and integrated circuits; therefore, it is an object of appreciable affair for packaging design to appraise the influence of misalignments during coupling. Efficient free-space coupling is predominant for achieving the communication systems with high bit rate at minimal loss values. Power coupling losses for lowest-order core-mode of large mode-area (LMA) hexagonal photonic crystal fibers (H-PCFs) in presence of misalignments (e.g., axial, radial and angular) with reference to input field is evaluated by utilizing the merits of an optical model. It is observed that LMA H-PCFs can be employed as appropriate aspirant for the efficient coupling strategy; moreover, theoretical results concerning coupling proficiency of classical SMF-28 are also studied. We investigated that LMA-10 PCF is not that sensitive to radial misalignment in contrast to the classical SMF; therefore, it can be utilized to frame manifold delays in optical true-time-delay (TTD) engines deployed on White cell concepts. The typical values of 1-dB tolerance are documented and the factors affecting coupling performance are also explored. Comparative results for the optimum butt-coupling loss are incorporated as articulated in the literature.
