As a kind of nanostructure device, Surface Plasmon Polaritons (SPPs) nanostructure filter can realize the effective manipulation of photons at nanometer or subwavelength scale. Among them, kinds of resonator-based multiplexer channel drop filters have been proposed and studied widely. However, a main problem is that the transmission efficiencies of such filters are relatively low. Thus, reflection cavities are designed for enhancing the transmission efficiency obviously. However, traditional demultiplexer usually requires several reflection cavities, because only one mode is utilized in a reflection cavity. In this paper, single reflection cavity is firstly designed to enhance the transmission efficiency of three channels at the same time via utilizing multiple modes in the reflection cavity. The theory and simulation analysis confirm the validity of such structure, the transmission efficiency of the three channels can be doubled. We believe this work provides novel notions for the design for demultiplexer filter.
Keywords: surface plasmons, wavelength filtering, multiplexing, subwave length.
Наноструктурный фильтр на основе поверхностных плазмон-поляритонов (Surface Plasmon Polaritons, SPP) позволяет обеспечить эффективные воздействия на фотоны, манипулируя на нанометровом или субмикронном уровне масштаба устройств. Предложенные и широко исследованные ранее разновидности фильтров для мультиплексорных каналов, однако, обладают общим недостатком – сравнительно низким уровнем пропускания. Введение в конструкцию отражающих наноразмерных одномодовых резонаторов приводит к повышению пропускания на их резонансной частоте. Однако для традиционных демультиплексоров, работающих на нескольких частотах, требуется введение нескольких различных резонаторов. В настоящей работе предложена конфигурация трёхканального демультиплексора, использующего один единственный резонатор, причём повышение пропускания для каждого из каналов достигается настройкой резонатора для его работы в многомодовом режиме. Теоретический анализ и компьютерное моделирование показали реализуемость этого подхода, приводящее к двукратному увеличению пропускания для каждого из трёх каналов.
