Abstract
Owing to recent advances in communications, the need of wider bandwidth is becoming more and more important. Therefore, much attention has been turned to optical communication. Traditionally, high-speed electronic components are used for the exchange of signals. However, they are not fast enough for signal transmission. Keeping signal transmission and exchange in the optical domain to increase the signal transmission rate must be the future trend. For this reason, optical switches potentially play important roles in optical communication.In this work, the thermo-optic switching is explored by using ultraviolet laser illuminated BCB optical waveguide devices. Experimental results show thermo-optic effects of channel waveguides and 2?2 multimode interference power splitters are successfully fabricated. For the channel waveguides, the output power is decreased by 12dB when the input power is 100mW. As for the 2?2 multimode interference devices, experimental results show, with an input power of 100mW, the switching of output powers can be successfully observed.
