ABSTRACT:
A waveguide device having a waveguide layer provided with a core and a cladding, and having a mode filter function of propagating either of TE mode polarized light and TM mode polarized light, wherein the core and the cladding are formed of a variable anisotropic refractive index material or a material in which a variable anisotropic refractive index material is dispersed in a matrix. Upon photoirradiation, the refractive indices (n.sub.o, n.sub.e) of the core and the cladding can be changed to satisfy the formulae: one of n.sub.o and n.sub.e of the core is greater than that of the cladding, and the other of n.sub.o and n.sub.e of the core is less than or equal to that of the cladding, wherein n.sub.o is the ordinary refractive index and n.sub.e is the extraordinary refractive index. This waveguide device can be an important constitutional component in a compact optical system. A method of producing the waveguide device is also disclosed.
