Width-modulated Half-Wavelength Pitch Silicon Waveguide Array for Dense Integration

In this work, we propose and demonstrate a compact low-crosstalk silicon waveguide array for dense integration of passive photonic devices. In this device, the waveguide pitch of the array is set to half of the working wavelength. To achieve low crosstalk, the widths of the waveguides in the array a...
