Abstract

Circularly bent gradient-index planar waveguides with finite cladding thicknesses are analyzed by the modal matching method. The waveguides assume the refractive index profiles of different shapes, namely, the parabolic and the truncated parabolic profiles. Numerical results of propagation characteristics together with pure bend loss are shown. In addition, feasibility of interferometric devices using bent planar waveguide is discussed.
