A hybrid optically interconnected microprocessor: an InP I-MSM integrated onto a mixed signal CMOS analog optical receiver with a digital CMOS microprocessor

摘要

This paper presents the results of simultaneously working fully-differential optoelectronic (OE) receiver fabricated in Si CMOS with digital SIMD microprocessor on the same die next to analog, optical interface circuittry, the receiver has been hybrid integrated with a thin film InP-based inverted (I)-MSM photodetector and optically tested using external light source modulated by digital input signal. The noise immunity to mixed-signal digital switching noise of the differential receiver has been shown to be good enough to generate 10~(-9) BER.
