Abstract

We fabricate a 20 µm wide grating coupler for a single-mode thermally-expanded-core (TEC) fiber, in order to enhance positional tolerance in alignment. The minimal coupling loss is measured at 5 dB per facet and the optical 3 dB bandwidth is measured at 40 nm. The 3 dB alignment tolerance is measured at ±7.5 µm in horizontal direction and +290 µm in vertical direction. The 1 dB alignment tolerance is measured at ±4.2 µm in horizontal direction and +125 µm in vertical direction. The alignment tolerance is enhanced twice in horizontal direction and four times in vertical direction, compared with the coupling of a standard single-mode fiber to a standard 10 µm wide grating coupler which is also fabricated in this experiment.

Simulated coupling efficiency to the conventional SMF from the 10 µm wide standard grating coupler in (a) and to the TEC fiber from the 20 µm wide grating coupler in (b), for various etching depths from 40 to 80 nm. (c) and (d) are simulated for the same conditions but the background refractive index with (a) and (b) respectively. The background index is the index of air in (a) and (b), when it is the index of BOX in (c) and (d). 70nm Exp in (a) and (b) is for experimental data in comparison with the simulated data.
