Measurement.

(a) Measured and simulated polarization conversion efficiency (PCE) as a function of metal length at the wavelength of 1550 nm. The blue squares are average of measured results. Error bar is the standard deviation. (b) Measured spectrum response of PCE and insertion loss (IL) for the device with wm = 140 nm and L = 2.5 μm.
