Abstract:
We present the design and optimization of 80-channel, 50-GHz Si3N4 based AWG. The AWG was designed for TM-polarized light with a central wavelength of 850 nm. The simulations showed that, while the standard channel count AWGs (up to 40) feature gut optical properties and are relatively easy to design, increasing the channel counts (> 40 channels) leads to a rapid increase in the AWG size and this, in turn causes the deterioration of optical performance like higher insertion loss and, in particular, higher channel crosstalk. Optimizing the design we are able to design 80-channel, 50-GHz AWG with satisfying optical properties.
