Abstract
A time-space-conversion optical signal processing using an arrayed-waveguide grating (AWG) is proposed. AWG consisting of two slab waveguides and a waveguide array is used in a reflection-type configuration. The first slab waveguide acts as a star coupler, the second one as a Fourier-transform lens, and the waveguide array functions as a dispersive element. A temporal waveform is converted to a frequency spectrum in the focal plane of the AWG. The frequency spectrum is then modulated in parallel by a spatial filter and reconverted to a reshaped temporal waveform. The AWG system is suitable for handling subpico- to several picosecond pulses with long time windows up to one nanosecond. Moreover, it is compact and compatible with fiber optics.
