“…Recently, a distributed wavelength routing/switching node based on tunable transceivers and AWGR with receiving, transmitting, and routing functions was proposed [6], which consists of transmitters (tunable laser TLD and modulator (MOD), receivers (PD), an electronic controller, and two N×N cyclic-AWG routers for the multiwavelength transmitter and receiver, respectively, as depicted in Fig. 2(a).…”

“…Management information (including topology information, network status, wavelength/path switching instructions, synchronization signal, etc.) between nodes can be exchanged using the pilot tone modulation technology with low-data-rate message channel [6], [18]. Each transmitter also performs the switching functionality using a tunable laser.…”

A monolithic 8×8 transmitter-router chip fabricated on InGaAlAs-InP multi-quantum well wafer for distributed wavelength routing network in the O-band with a channel spacing of 400 GHz is experimentally demonstrated. A tunable V-cavity laser (VCL) array, a cyclic-arrayed waveguide grating router (AWGR) and a semiconductor amplifier (SOA) array are integrated using the quantum-well intermixing (QWI) technique for its fabrication simplicity and cost effectiveness. A 200 GHz-spaced compact-size VCL is demonstrated with a 27 nm tuning range and a side-mode suppression ratio (SMSR) around 40 dB using a single-electrode controlled tuning. The chip output power is 24.6 mw. Measurement results of the transmitter-router chip show that all 64 input-output combinations have cyclic response spectra. After passing through the SOA with 80 mA bias current, an output power of about 9.6 mW and optical signal-to-noise ratio (OSNR) up to 39 dB have been measured. The demonstrated transmitter-router chip is fabricated on the same quantum well structure without requiring multiple epitaxial growth and complex grating fabrication. The characteristics of multi-wavelength and multi-port transmissions enable the distributed optical routing networks with flexible bandwidth allocation, which can find wide application in datacenters and high-performance computers.
