The World’s First InP Eight-Channel Monolithic Tunable Optical Router (MOTOR)
Tech ID: 20560 / UC Case 2010-265-0
Brief Description
The world’s first 8x8 monolithic tunable optical router (MOTOR) in InP.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.Description
Researchers at the University of California, Santa Barbara have developed the world’s first 8x8 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.

The 8-channel InP monolithic tunable optical router, or MOTOR, produced by University of California, Santa Barbara, scientists. The left half of the chip holds eight wavelength converter arrays, and the right holds the arrayed waveguide grating router.
