“…For simplicity, we denote λ o as the difference between the actual and designed values of λ o . Note that the wavelength-dependent splitting ratio of a DC with arbitrary w i and h i can generally be calculated in theory [17], then the λ o can be obtained. Fig.…”

“…According to our simulations, such an approach can be scaled up to arrays of at least 50 waveguides with dimensions as described above and maintain crosstalk less than 10 dB. Even larger array sizes can be reached by varying waveguide geometry in adjacent elements in order to cause group index mismatch, which has been shown to allow propagation of up to 500 μm at short spacing [28,29]. We began fabrication with a Soitec® silicon-on-insulator wafer with a 3-μm buried oxide layer.…”

“…An eleven-channel mode MUX comprising two sub-arrays of five single-mode waveguides is exhibited. The theoretical framework and design guidelines for DPWAs to generate supermodes having low crosstalk are provided comprehensively [72,73]. Another possible way to break the phase matching condition is to introduce bent waveguide array where the waveguides have the same width but different bend radius.…”
