We present DWDM nanophotonics architectures based on microring resonator modulators and detectors. We focus on two implementations: an on chip interconnect for multicore processor (Corona) and a network that uses high-radix switches (HyperX). Based on the requirements of these applications we discuss the key constraints on the photonic circuits' devices and fabrication techniques as well as strategies...
We show a direct comparison between silicon reconfigurable delay lines based on coupled resonator optical waveguides and photonic crystal waveguides. The structures are used to selectively delay the two orthogonally polarized channels of a RZ-PolDM-DQPSK format at 100 Gbit/s.
We have used a urethane polymer as cladding to reduce the temperature sensitivity of resonance in high-Q silicon microdisk resonators. A two-order-of-magnitude improvement in resonance stability is demonstrated, and effects on the Q-factor are discussed.
We demonstrate a distortion free tunable delays as long as 72 ps with a 10 GHz bandwidth using thermally tuned silicon microring resonators. The device is compact measuring only 30 mum wide by 250 mum long.
A low loss sharp bend is proposed and analyzed in the slow-light waveguide which is consisted of a series of silicon nanopillars. More than 90% of transmission over 100 nm bandwidth is obtained.
