Abstract :
Design of a compact polarization rotator (PR) exploiting power coupling through phase matching between the TM mode of a strip waveguide (WG) and TE mode of a vertical slot WG is presented. Optimized cross sectional dimensions of the coupler have been achieved to use this device as a compact PR at 3 μm wavelength with device length of just 2 mm. We also investigate the device performance at the operating wavelength (λ) = 1.55 μm.
