IIIV/Si hybrid integrated devices for optical interconnect
2015
We discuss our view of the on-chip optical interconnect infrastructure for future multi-core processers based on
wavelength-division-multiplexing (WDM) and our recent results on some key devices for such structures. Cascading
performance of various wavelength multiplexers and de-multiplexers including arrayed waveguide gratings (AWGs) and
echelle gratings based on the silicon-on-insulator platform are discussed and compared. IIIV based electro-absorption
(EA) modulators on silicon realized through benzocyclobutene (BCB) adhesive bonding are analyzed. Ultra short
adiabatic taper based mode converters between passive and active structures are designed. The integration of multichannel
modulators, detectors and wavelength de-multiplexers is realized.
