Abstract

Organic light-emitting diodes (OLEDs) are a most promising candidate for light sources of the compact optoelectronic integrated neural (COIN) coprocessor because of their easy integration with the silicon electronics. However, the optical properties of OLEDs are different from those of vertical-cavity surface-emitting lasers, which were previously used in the COIN system. The interconnect behavior of the COIN coprocessor is unknown if OLEDs are employed. In this paper, we build a mathematical model of the interconnect scheme of the COIN coprocessor and investigate the influence of the spectral bandwidth, light-emitting area, and angular emission profile of OLEDs by numerical simulations. The simulation results show that OLEDs with properly selected properties can be used as the light sources for the COIN coprocessor.
