A hybrid electrical-optical circuit board is demonstrated using polysiloxane as low-loss and high-temperature stable waveguide material system. After board lamination at 180°C for two hours and a subsequent annealing at 230°C for 5 minutes the waveguide insertion loss is 0.05 dB/cm at 850 nm wavelength.
