COMPACT OPTICAL WAVEGUIDE ARRAYS AND OPTICAL WAVEGUIDE SPIRALS

摘要

can reduce the crosstalk in the optical waveguide bundle by changing the width of the individual waveguides. Using a waveguide of different widths reduces the increase of the crosstalk between the optical wave guide and, thereby, by according to the wave guide can be located closer, increasing the waveguide density on a chip, and / or reduce the routing space required for the waveguide bundle thereby. Further, according to the cross-talk can be reduced to vary the width of the spiral waveguide, it is possible to increase the power efficiency, even if implemented in a coiled or folded waveguide thermal optical (TO) device.
