“…Currently many silicon-based on-chip polarizers with decent performances have been reported . Basically speaking, a polarizer can be realized by manipulating the polarization-dependence of the propagation loss [24,25], the cut-off condition [26][27][28][29], or the field profiles of the guided-modes in optical waveguides [30,31]. For example, an on-chip polarizer was realized with the TM 0 -TM 1 coupling in an asymmetric directional coupler (ADC) [24], which enables a high ER of >15 dB in a broad wavelengthband over 80 nm.…”

“…In order to achieve compact and broadband high-performance polarizers, great efforts have been made in recent years. In particular, the special structures based on SSWGs [26][27][28][29][30][31] as well as HPWGs provide promising approaches for realizing ultra-short optical polarizers, as summarized in Table 1.…”

“…Adiabatic tapers, designed using the Fourier modal method [32], are used to transition from wide waveguides to single-mode width inter-row U-bends without exciting higher order modes. The inter-row U-bends are designed for ultra-low insertion loss by employing an adiabatically varying curvature [33,34] that minimizes bend loss without junction losses. The predicted and measured component losses are shown in Fig.…”

“…5(a) shows the optical microscope image of the fabricated MZI structure. An on-chip low-loss TE-pass polarizer [24] was used at the output section of the MZI to eliminate any unintentionally excited TM polarization. SEM images of the important sections of the MZI are shown in Figs.…”
