Abstract
An asymmetric Y-junction wavelength demultiplexer, with a segmented br anch, was realized in Ti:LiNbO3. The device was fabricated in a single -step lithographical process. Wavelength demultiplexing operation in t he range 633 nm<lambda<834 nm is demonstrated, with extinction ratios up to 30 dB. Insertion loss vary between a negligible value (far away from cutoff) up to 7 dB (near cutoff). Possible applications of the de vice are considered. (C) 1995 American Institute of Physics.
