Ultra-Wideband Edge Coupler Based on SubWavelength Grating Slot Waveguide (SWGS)
We design an edge coupler utilizing subwavelength grating slot (SWGS) waveguide structure, achieving ultra-low coupling losses in the range of 1480nm to 1640nm. We achieve coupling losses of less than 1.5dB /facet through experimentation. © 2024 The Author(s)
