We review the use of the oxide cladding stress induced photoelastic effect to eliminate the modal birefringence in silicon-on-insulator (SOI) ridge waveguide components, and highlight characteristics particular to high index contrast (HIC) systems. The birefringence in planar waveguides has its origin in the electromagnetic boundary conditions at the waveguide boundaries, and can be further modified by the presence of stress in the materials. It is shown that geometrical constraints imposed by different design and fabrication considerations become increasingly difficult to satisfy with decreasing core sizes. On the other hand, with typical stress levels of -100 MPa to -400 MPa (compressive) in SiO₂ used as the upper cladding, the effective indices are altered up to the order of 10^-3 for ridges with heights ranging from 1 μm to 5 μm. We demonstrate that the stress can be effectively used to balance the geometrical birefringence. Birefringence-free operation is achieved for waveguides with otherwise large birefringence by using properly chosen thickness and stress of the upper cladding layer. This allows the waveguide cross-section profiles to be optimized for design criteria other than zero-birefringence. Since the index changes induced by the stress are orders of magnitude smaller than the waveguide core/cladding index contrast, changes in the mode profiles are insignificant and the associated mode mismatch loss is negligible. We study the stress-induced effects in two parallel waveguides of varying spacing, to emulate the condition in directional couplers and ring-resonators. In the arrayed waveguide grating (AWG) demultiplexers fabricated in the SOI platform, we demonstrated the reduction of the birefringence from 1.3x10^-3 (without the upper cladding) to below 1x10^-4 across the spectral band by using a 0.6 μm oxide upper cladding with a stress of -320 MPa (compressive). Design options for relaxed dimensional tolerance and improved coupler performance made available by using stress engineering are discussed.

The high index contrast of silicon-on-insulator (SOI) enables the scaling down of planar waveguide components into the microphotonic regime, but has the unwanted consequence of inducing a large TE-TM polarization birefringence. For ridge waveguides this birefringence can be reduced to an acceptable level by using appropriate ridge dimensions [1], but with decreasing Si thickness the required fabrication tolerances quickly become too narrow to implement this solution. Components with slab waveguide regions such as echelle grating demultiplexers cannot be made polarization independent using this method. An alternate approach is to introduce a polarization compensation region in the combiner section of an AWG or echelle grating to eliminate the polarization dependent wavelength shift[2]. In its original implementation, the compensator is fabricated by changing the local waveguide thickness. The resulting birefringence correction can be sensitive to errors in etch depth, and the mode mismatch between compensator and slab waveguide sections is a source of approximately 1 dB extra insertion loss (IL) for SOI demultiplexers with Si waveguide thickness in the range from 2 to 5 m. We describe a new compensator structure for the SOI platform using a buried low index layer, in this case SiO2 sandwiched between the Si waveguide layer and another Si cap layer. Such a silicon-oxide-silicon (SOS) compensator on SOI can eliminate the TE-TM wavelength shift of an SOI AWG or echelle grating demultiplexer without introducing a significant mode mismatch between the compensator and slab waveguide sections. A demultiplexer with an SOS compensator has almost 1 dB lower insertion loss of an equivalent device with an etched compensator. The SOS compensator is easily implemented using standard oxide and a-Si or polysilicon deposition techniques. In this paper we present calculations and experimental results on the effective birefringence compensation, PDL and IL of SOS compensators in SOI waveguide demultiplexers.
