Abstract:
We show an improved fabrication process of trapezoidal polarization converters for InP-based photonic integrated circuits. The new process has reduced complexity, and the fabricated converters have loss two times lower than reported previously. The measurements of the converters show an efficiency of polarization conversion of 97.9% at a wavelength of 1.535 μm and loss below 0.5 dB.
