Dispersion effects in a single-mode holographic waveguide interconnect system

Dispersion effects in a single-mode holographic waveguide interconnect system are analyzed, and the effect of a wavelength shift in laser diodes owing to the variation of environmental temperature are discussed. It is found that the stringent coupling-in requirement of the single-mode waveguide is the limiting factor of the optical interconnect performance. A novel waveguide grating coupler is thus introduced to eliminate this problem.
