A Compact and Broadband Splitter to Interface Between Strip and Slot Waveguides
We demonstrate a compact and low-loss 1 × 2 power splitter that efficiently splits and couples light from one strip to two slot waveguides. The splitter is optimized over a broad wavelength span ranging from 1.3 to 1.7 <inline-formula><tex-math notation="LaTeX">${\mu...

| description | We demonstrate a compact and low-loss 1 × 2 power splitter that efficiently splits and couples light from one strip to two slot waveguides. The splitter is optimized over a broad wavelength span ranging from 1.3 to 1.7 <inline-formula><tex-math notation="LaTeX">${\mu }$</tex-math></inline-formula>m through finite difference time domain simulations. The splitter junction footprint is only 2.00 × 1.61 <inline-formula><tex-math notation="LaTeX">${\mu }$</tex-math></inline-formula>m. The structure does not require an adiabatic transition region and is compatible with standard commercial silicon photonic fabrication processes. Experimental results show an insertion loss of less than 0.7dB for the TE polarization. |
