Benzocyclobutene polymer in glass multimode interference thermo-optic switch

Optical switch fabrics are integral parts of optically switched network because these devices are capable to direct input traffic to the appropriate output interface without resorting to optical-to-electrical-to-optical (OEO) conversion. This thesis is significantly devoted towards the design and si...
