Abstract :
Wavelength demultiplexer fabricated on electrooptic LiNbO3 is demonstrated. Reflection structure was employed to halve the device length. The full width at half maximum of the transmission peak was around 1 nm. The crosstalk was -12 to -25 dB. Polarization independence was attained using a reflective quarter-wave plate
