Silicon photonics is a rapidly progressing field, where silicon structures are developed
for optical information generation, transmission and processing. Although substantial
progress has been achieved in the fields of transmission and processing,
significant challenges remain to be addressed in generating light on silicon. In this
paper we show that by integrating a silicon resonator with organic semiconductors,
light generation on silicon chips can be achieved in the visible spectral range. Unlike
similar attempts in the telecommunication spectral region, the signal from our device
can be directly measured by silicon photodetectors.
