Abstract

The direct butt-coupling technique for fiber–chip coupling yields a 7–10 dB power loss because of the unequal spot-sizes associated with each device. We design a fiber ended micro-lens to enhance the coupling efficiency and further derive the meridian expression. To meet the needs of the sub-micron alignment tolerance, a self-aligned mounting is developed, and electro-strictive actuators are employed. Along with the reference alignment solution, alignment feedback and control can be realized..

Keywords
