With the advances in semiconductor circuit integrated technology and optical device integrated technology

the trend of applying optical transmission technology to chip is irresistible

This paper describes the development of on-chip transmission

on this basis

analyses its requirments of bandwidth

latency and throughput etc.and dicusses the method that how to apply optical transmission technology to chip.In addition

we investigate the background information of on-chip optical transmission system.What is more

details of a on-chip optical transimition application including its network architecture design

router design and communication process are presented.Finally we predict the trend of on-chip optical transmission.
