Abstract

The waveguide array grating demultiplexer [1] exhibits wavelength routing that makes it suitable for many types of systems using wavelength multiplexing technique. Thus far, the device has been fabricated using a SiO₂, compound semiconductor and polymer. We report a device fabricated using LiNbO₃, an excellent electro-optic crystal that has been used in a wide variety of guided-wave devices. A polarization-independent device is obtained using a quarter -wave plate and a mirror.
