We experimentally demonstrate apodized focusing subwavelength grating couplers for both the fundamental transverse electric (TE00) mode and the fundamental transverse magnetic (TM00) mode. A measured insertion loss of 3.2 dB with a 1-dB bandwidth of 36 nm has been obtained for the TE00 mode, and a measured insertion loss of 3.3 dB with a 1-dB bandwidth of 37 nm has been obtained for the TM00 mode. Back reflections of -24 dB and -21 dB have been obtained for the TE00 and TM00 modes, respectively.
