Abstract :
A novel directional-coupler optical switch based on the concept of the field-induced guide is demonstrated for the first time. The device exhibits a good switching characteristic between two output ends with a crosstalk of -10 dB at a 1.15 mu m wavelength for a device with an 800 mu m coupling length.
