A broadband silicon PSR is presented with an insertion loss lower than ∼0.7dB/0.3dB and crosstalk lower than 12.1dB/14.7dB for TE and TM mode respectively. By combining the PSR with AWG and Germanium PDs, an integrated polarization insensitive DWDM receiver is further demonstrated.
The ability to manipulate polarization of light on a chip is of fundamental importance for many applications. Here, we demonstrate an ultrabroadband quarter-wave plate for silicon photonics based on pure dielectric waveguides. The concept of birefringence is used to introduce a phase lag of π/2 between two orthogonally polarized modes in nanophotonic waveguides, such that a quasi-linearly polarized...
In this paper, two kinds of compact waveguide structures based on through glass vias (TGVs) technology are proposed. A full-wave simulator on the basis of finite element method is applied to analyze the transmission characteristics of these structures. The return loss S11, transmission S21 and electric field distribution results show that they have the similar signal transmission performance of the...
We discuss titanium dioxide material development for CMOS compatible fabrication and integration of athermal silicon photonic components. Titanium dioxide overclad ring modulators achieved athermal operation (< 0.2 GHz/°C).
