Abstract :
We analyze the latency in three optical receiver circuit architectures intended for short optical interconnects. We compare the latency for interconnects using (i) non-return to zero (NRZ) modulation format, and (ii) modulation of short optical pulses ( 1ps). We find that the use of short optical pulses in modulator based interconnects offers the potential of a significant reduction in latency. In this paper we assume that the GaAs p-i-n modulators and diodes are hybrid integrated on 0.25 μm CMOS circuits
