Assessment of Low Polarization Dependent Multicast and Select Switch Based on Bulk SOA for Data Center Application
Aref Rasoulzadeh Zali;Netsanet M. Tessema;Steven Kleijn;Luc Augustin;Ripalta Stabile;Nicola Calabretta
We have designed, fabricated, and characterized a low polarization dependent multicast and select (MCS) switch based on a newly developed novel bulk SOA co-integrated with passive waveguides. The proposed new bulk SOA-based MCS switch requires the co-integration of active SOAs (gate and booster) with several passive InP elements. First, we have presented a theoretical analysis and the design and p...Show More
