Abstract

An optical switch based on a single-mode fused coupler has been fabricated. The switch is worked by light induced refractive index change of an organic photochromic compound as cladding material in the coupling region. The splitting ratio of optical output at 1.3 μ m wavelength light can change 44.5%. The optical loss in the switch is less than 0.4
