We demonstrate a new approach of fabricating a thermo-optic polymer-waveguide Mach-Zehnder interferometer (MZI). The MZI is fabricated with an imprinting technique, where the electrode heater is formed at the bottom of the waveguide substrate.
We review our recent works on the realization of planar lightwave circuit (PLC) technology-based optical interleavers. Commercially available polymer materials were used to fabricate the devices and we implemented our designs using two different configurations. The first is based on a folded two-stage-cascaded Y-junction MZI interleavers which offers a flat-top 100 GHz channel spacing over the entire...
Using nematic liquid crystal as the upper cladding of inverted polymer waveguide structure, we fabricated a variable optical attenuator which exhibited a 24 dB of attenuation range with a tuning range of 10 Vpeak at 1550 nm.
