“…The mode-beating waveguide elements described previously, along with a polarisation mode splitter [19], [20] (equivalent of a polarising beam splitter) can be combined in a number of ways to provide functional polarisation devices as shown in Fig. 7.…”

“…This range of polarisation states has a modulus ranging from 0 to 1 for the TE-and TM-polarised components achieving amplitude modulation with a polarisation discrimination element. Reference [20] includes a schematic of such a polarisation-based amplitude waveguide modulator where the R-PMCs correspond to quarter-beat-length of 100% converters and the differential phase shift is provided by Pockel's electro-optic effect. A similar approach has also been described for a polarisation controller with cascaded elements consisting of orientated, spliced birefringent optical fibre sections and thermo-optic modulation [21].…”

A toolset of waveguide elements is examined which can be combined to produce polarisation functional devices in a single contiguous waveguide. In particular waveguide implementations of an optical isolator and a polarisation modulator are discussed. The waveguide elements: quasiphase-matched nonreciprocal polarisation mode converter, reciprocal polarisation mode converter and a differential phase shifter, are all based on mode-beating. A universal 3 dB reciprocal polarisation mode converter specification is identified which suffices for all the polarisation functional devices considered here. A full-vectorial modesolver is used to determine the modes in a number of example III-V waveguide structures and the polarisation state evolution is considered by using an averaged Stokes vector illustrated on the Poincar é sphere construct.

“…A polarization modulator can be realized by combining one or more PMC sections with Differential Phase Shifting (DPS) sections. These DPS sections provide birefringence in a symmetric waveguide and in principle, light can be converted from one polarization state into any other state [2] [7].…”
