Abstract :
A planar lightwave circuit based device is proposed that can recognise optical multiwavelength pulse patterns based on digital-to-analogue conversion. The device consists of a splitter with variable splitting ratios, delay lines and an arrayed-waveguide grating based wavelength multiplexer, and requires no optical gates. 80 Gbit/s and four-bit label recognition experiments were successfully carried out with the device.
