Paper Abstract

In this paper, the input-output coupler system using two and three Bragg gratings is implemented for optical communication wavelength, i.e. 1550nm, in path-folding and path-shifting type. The grating is designed with 45 degrees fringe slant angle to achieve normal direction input, output coupler. An additional grating at the output coupler makes the total system throughput increase 9% in comparison with two-grating input-output coupler system. With 5x5mm grating size, the total systems throughput can reach nearly 26% for two-grating and 35% for three-grating input-output coupler.
