主 题：interferometer polarization modulator
摘 要：Strongly influenced by the advances in the semiconductor industry,the miniaturization and integration of optical circuits into smaller devices has stimulated considerable research efforts in recent *** other structures,integrated interferometers play a prominent role in the development of photonic devices for on-chip applications ranging from optical communication networks to point-of-care analysis ***,it has been a longstanding challenge to design extremely short interferometer schemes,as long interaction lengths are typically required for a complete modulation *** approaches,including novel materials or sophisticated configurations,have been proposed to overcome some of these size limitations but at the expense of increasing fabrication complexity and ***,we demonstrate for the first time slow light bimodal interferometric behaviour in an integrated single-channel one-dimensional photonic *** proposed structure supports two electromagnetic modes of the same polarization that exhibit a large group velocity ***,an over 20-fold reduction in the higher-order-mode group velocity is experimentally shown on a straightforward all-dielectric bimodal structure,leading to a remarkable optical path reduction compared to other conventional ***,we experimentally demonstrate the significant performance improvement provided by the proposed bimodal photonic crystal interferometer in the creation of an ultra-compact optical modulator and a highly sensitive photonic sensor.
