Abstract
We report the design and fabrication of a compact angled multimode interferometer (AMMI) on a 600nm thick N-rich silicon nitride platform (n=1.92) optimised to match the International Telecommunication Union (ITU) coarse wavelength division (de)multiplexing (CWDM) standard in the O telecommunication band. The demonstrated device exhibited a good spectral response with ∆λ=20nm, BW3dB ∼11nm, IL<1.5dB and XT∼20dB. Additionally, it showed a high tolerance to dimensional errors <120pm/nm and low sensitivity to temperature variations <20pm/ºC, respectively. This device had a footprint of 0.02×1.7mm2 with the advantage of a simple design and a back-end-of-line compatible fabrication process that enables multilayer integration schemes due to its processing temperature <400ºC.
