Researchers at the University of California, Santa Barbara have developed the world’s first 8×8 monolithic tunable optical router (MOTOR) in InP. The device represents one of the most densely-integrated InP chips ever reported, with more than 200 integrated functions. The device exhibits error-free operation at 40 Gbps with a power penalty as low as 4.3 dB.

Background
Advanced photonic integrated circuits in InP are a critical technology for next-generation optical networks. Photonic integrated circuits provide a reduce device footprint and the elimination of component-to-component coupling losses. Although devices like advanced transmitters and wavelength converters that exploit these benefits have been realized, there have only been a few demonstrations of large-scale integration in InP.
