Materials and Fabrication Issues of Optical Fiber Array

Photonic devices are becoming widespread as an advanced information-communications network of the 21st century. With the increased use of photonic devices, there is a need for optical connecting path between photonic devices. The optical fiber array is such a smart approach for all optical functionality of the optical chip without any need of electrical wiring. However, it remains a challenge to develop the reliable fabrication know-how in manufacturing of fiber array. This paper will discuss the issues required in the reliable fabrication of optical fiber array, and integrating them to address the future needs of the information and communication technology sector. Issues affecting the quality of the optical fiber array mainly include the material selection, processing condition, and bonding technique. The advantages and disadvantages of each materials and fabrication method are discussed with the major failure issues. The findings can serve as a guide for optimizing the materials and process parameters in the reliable fabrication of optical fiber array in Photonic industry.
