An AWG based optical router

Optical packet switching is considered as next generation data transfer technology in conjunction with mature electronics. In the design of optical routers, the main issue is the splitting loss of the devices and control unit complexity. Hence, much research has been done in designing of the simple routers. This exploration leads to generation of AWG based optical routers. In this paper, AWG based optical router is discussed and simulation results are presented in terms of packet loss probability for symmetric and asymmetric switch. It is also shown that in the earlier architecture, due to the unequal power of the buffered and directly transmitted packets, some of the buffered packet may not fully utilize the buffer capacity due to the degraded quality of the packets in the buffer. However, in the modified architecture, the buffer capacity is fully utilized effectively.
