We review our recent results on the linear optical sampling (LOS) enabled all-optical modulation format analyzer. Precise characterizations of arbitrary 128 Gbps PDM-QPSK wavelength channel from 1550 nm to 1570 nm are successfully achieved, when a 101.3 MHz frequency spaced comb with 3-dB spectral power ripple of 20 nm is used.
