摘要: An optical switch using an adjustable Y-junction structure has been designed, fabricated, measured, and analyzed. Both the experimental performance theoretical prediction of are presented. The switching section device consists three arrow-shaped, field-induced waveguides that overlap in propagation direction such input light from middle guide can be transferred to either output guides. A cross talk less than -18 dB is measured at a wavelength 1.06 microm with transition length 400 branching angle 4 degrees . Numerical simulations finite difference beam method show -22 may achievable for these dimensions.
