Loss reduction of AS/AC networks with holographic optical switches
Jiun-Shiou Deng, Chien-Yi Lee, Ming-Feng Lu, Yang-Tung Huang · 2007
Using holographic optical switches to implement active splitter/active combiner networks not only significantly save the space of the whole system and efficiently eliminates all interconnection lines and crossovers, but also reduces the number of switches from 2N-2N to 2Nlog2N. The system insertion loss can also be significantly minimized by combining the unique features of the active splitter/active combiner network and holographic optical switches. Key-words: holographic optical switch, optical switch, polarization beam splitter, optical interconnection network, system insertion loss, polarization selective element.
