Polymer multimode optical waveguides were fabricated from optically-sensitive hybrid silicone using the ultraviolet laser drawing method. The waveguide loss values were measured as 0.069 dB/cm with a laser diode, 0.069 dB/cm with a vertical-cavity surface-emitting laser, and 0.128 dB/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 47 dB and 0.5 dB, respectively.
