Fabrication of multiwavelength simultaneous monitoring device using arrayed-waveguide grating

The authors demonstrate a novel multiwavelength simultaneous monitoring (MSM) device using silica-based arrayed-waveguide grating (AWG). In the present MSM device, the spectral transmission loss characteristics of the two diffraction beams are devised to cross at the signal wavelength. It is applicable to the unequally spaced WDM systems aiming at the suppression of four-wave mixing problems. The slope coefficient of the discrimination curve was /spl sim/0.94 dB/GHz and the monitoring range was /spl plusmn/0.37 nm in the fabricated MSM for use in 8 ch unequally spaced WDM systems.
