Paper Abstract

Single-mode channel waveguides with a wave propagation loss below 0.1 dB/cm and good matching to the profile of the single-mode fiber can be manufactured by means of two-step field-assisted Cs+-K+ ion-exchange in BGG 21 glass. This technique has been used in the manufacture of symmetrical lxN (N = 2,4,8) couplers and asymmetrical Y-junctions as power dividers. Dual-channel wavelength-division multi/demultiplexers consisting of symmetrical directional couplers or zero-gap couplers have been built in glass and analyzed. In the 1.2/1.6 μm wavelength range, insertion losses below 2 dB, channel spacings of 50-180 nm, and crosstalk values of 20-35 dB have been attained.
