Abstract

An indium phosphide-based monolithically integrated wavelength router is demonstrated in this Letter. The wavelength router has four input ports and four output ports, which integrate four wavelength converters and a $4\times 4$ arrayed-waveguide grating router. Each wavelength converter is achieved based on cross-gain modulation and cross-phase modulation effects in a semiconductor optical amplifier. Error-free wavelength switching for a non-return-to-zero 2³¹–1 ps eudorandom binary sequence at 40 Gb/s data rate is performed. Both $1\times 4$ and $3\times 1$ all-optical routing functions of this chip are demonstrated for the first time with power penalties as low as 3.2 dB.
