A silicon photonics based fiber interconnect is presented including an integrated node-matched-diode modulator and Ge-photo detector. Due to very small footprints, a single channel 25 Gb/s non-return-to-zero data rate corresponds to a photonic bandwidth density of about 0.5 Tb/(s·mm2).
We show how k-space spectroscopy distinguishes between the surface-plasmon (SP) and photon nonlinear interactions for SHG when metal films are excited in the Kretschmann-geometry, and confirm that two SP annihilate to create a second-harmonic photon.
Feasibility of a tunable delay of optical data streams is proved by experimentally validating a hybrid fiber/integrated realization. Ultimate design can provide delays of more than 200 ps in an area of about 0.4 mm2.
