Abstract :
Hybrid integrated cascaded 1 times 4 electrooptic (EO) polymeric digital optical switches (DOSs) are proposed and demonstrated. The hybrid integration of passive polymer on the same chip with EO polymer can lower the overall device loss without affecting the EO effects. The cascaded DOS can be controlled by only two voltage signal sources without bias stabling mechanism. The device can be operated as a 2-bit reconfigurable switch. The switching voltage is around 15 V for single arm driving with reasonable extinction ratio (9~12 dB) and the loss is improved by ~2.5 dB. This device is ideal for implementing variable optical delay network
