Abstract
Polymer multimode optical waveguides were fabricated from optically-sensitive hybrid silicone using the ultraviolet laser drawing method. The waveguide loss values were measured as 0.069dB/cm with a laser diode, 0.069dB/cm with a vertical-cavity surface-emitting laser, and 0.128dB/cm with a light-emitting diode. The cross waveguide on a curved waveguide was drawn by overlapped direct laser drawing. The crosstalk and excess loss at the cross angle of 50° in the cross waveguide were measured as 47dB and 0.5dB, respectively.
