“…The proposed PBS has a better PER than the work presented in [7,9,11,15]. The work presented by Fraunhofer group in [10] has a better performance, nevertheless, to overcome the fabrication tolerances the device uses thermal tuning, which has a difficult calibration. This issue is solved by the work presented in [12].…”

“…All of them have in common that they have tight fabrication tolerances. There are several designs that try to overcome such tolerances like the one presented in [9] that uses a Periodic Layer Structure of Si/SiO2 or the ones [10][11] that uses thermal tuning. One of the main disadvantages of using the PLS is that it adds complexity to the fabrication.…”

“…There are some reports of PBS in InP that try to relax or ease fabrication tolerances using different techniques such as Si/SiO 2 Periodic Layer Structures (PLS) [10] or thermal tuning [9,11,12]. In the case of the PLS, this adds complexity to the fabrication, requiring the deposition of many layers in a periodic stack.…”

“…This device separates the TE mode from the TM mode within the integrated circuit. Several polarization beam splitters in both silicon [3][4][5][6][7] and indium phosphide (InP) have been demonstrated [8][9][10][11]. One of the major fabrication issues for the PBS in both Si and InP is that they have stringent fabrication tolerances in order to produce a high extinction ratio.…”

Abstract:In this work, a novel highly fabrication tolerant polarization beam splitter (PBS) is presented on an InP platform. To achieve the splitting, we combine the Pockels effect and the plasma dispersion effect in a symmetric 1x2 Mach-Zehnder interferometer (MZI). One p-i-n phase shifter of the MZI is driven in forward bias to exploit the plasma dispersion effect and modify the phase of both the TE and TM mode. The other arm of the MZI is driven in reverse bias to exploit the Pockels effect which affects only the TE mode. By adjusting the voltages of the two phase shifters, a different interference condition can be set for the TE and the TM modes thereby splitting them at the output of the MZI. By adjusting the voltages, the very tight fabrication tolerances known for fully passive PBS are eased. The experimental results show that an extinction ratio better than 15 dB and an on-chip loss of 3.5 dB over the full Cband (1530-1565nm) are achieved.

Photonic integrated circuits (PICs) suffer from birefringence due to high-index contrast. Polarisation handling devices improve the performance of the PICs by reducing the polarisation-dependent dispersion and loss. Furthermore, there is a growing interest in building polarisation division multiplexed transceivers using PICs, which require polarisation management. The authors provide an overview of the recent work on developing polarisation handling devices such as polarisation beam splitters and polarisers in indium phosphide and silicon-on-insulator platforms for optical communications and sensing applications. These devices expand the PICs library of polarisation handling devices and can be used to design more complex circuits with advanced or new functionalities. Polarisation beam splittersPBS is the basic building block in polarisation diversity circuits, which splits and combines light with different polarisations. The incoming signal polarisation is separated into two orthogonal polarisations (TE and TM) using a PBS, which enables
