Abstract
In this contribution we present an accurate investigation of an integrated optical polarizer. We evaluate the TM-pass property for an asymmetrical slab with an anisotropic cover. We select a dielectric multilayer cladding (that behaves as negative uniaxial crystal) based on Si and Si02 with isotropic core. We then analyze the positive case by using: 1) as cladding many identical parallel cylindrical bars of small diameter, surrounded by uniform material; 2) as core gallium arsenide (GaAs). Subsequently, we validate the model by means of the hybrid TLMIE method and provide design criteria for a rib polarizer with negative uniaxial cover. The proposed polarizer is realized by using a single-mode channel. By utilizing the TM-passing property of the anisotropic cover we select the polarizationI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
