We present an air-cladding apodized focusing subwavelength grating that can effectively couple two polarizations into a single waveguide. For the transverse magnetic mode, 3.2dB maximum coupling efficiency with 28nm 1 dB bandwidth is achieved. With the same grating, 4.3dB maximum coupling efficiency with 58nm 1 dB bandwidth is achieved for the transverse electric mode. The minimum difference between two polarizations’ coupling peaks is demonstrated to be 32nm. At the 1525 nm wavelength range, the polarization-insensitive grating is demonstrated with 6.5dB coupling efficiency. The polarization-insensitive coupling wavelength can be controlled experimentally.
