Abstract :
Summary form only given. There has been growing interest in glass waveguide wavelength demultiplexers for applications in optical fiber communication systems. The device to be presented is shown to consist of two waveguide branches are made by K/sup +/-Na/sup +/ ion exchange with its arm 2 cladded by an Al/sub 2/O/sub 3/ layer. The demultiplexing is based on the difference in the dispersion characteristics of the two asymmetric branches. In a previous paper the difficulties were mainly with the deposition of a reliable Al/sub 2/O/sub 3/ layer. In this paper, we will present a much improved BPM design simulations, fabrication techniques and performance figures of this device.
