It allows for singlemode single polymer waveguides with large cross-sections, despite considerable index differences between core and cladding layers. Results of waveguides fabricated from a commercially available, high temperature stable polymer (T(ind g)>350°C) are presented, indicating losses of below 0.5 dB/cm at 1.3 µm.endesign conceptsingle-mode waveguides621384Design concept for singlemode polymer waveguidesjournal article
