Abstract
In this paper we present the size reduction of a 160-channel, 50-GHz Si3N4 based AWG-spectrometer. The spectrometer was designed for TM-polarized light with a central wavelength of 850 nm applying our proprietary “AWG-Parameters” tool. For the simulations of AWG layout, the PHASAR photonics tool from Optiwave was used. The simulated results show satisfying optical properties of the designed AWG-spectrometer. However, such high-channel count AWG features large size. To solve this problem we designed a special taper enabling the reduction of AWG structure by about 15%, while keeping the same optical properties. The technological verification of both AWG designs is also presented.
