WAVEFRONT FORMATION IN GRADIENT WAVEGUIDES WITH SMALL RADIUS BENDS

G. L. Esayan and S. G. Krivoshlykov

Abstract:
Propagation of light radiation through sharply bent units of multimode waveguides with quadratic refractive index profiles is theoretically investigated. Expressions have been derived for coefficients of mode coupling and for the energy loss on the bends. Using the results obtained it is proposed to use bent waveguides as mode filters operating in the matched mode and also as adjustable-sensitivity refractometers.
