“…Therefore, the reflection coefficient of PLHWC is obtained from (7) It is shown that the reflection coefficient of PLHWC is the same as that of the conventional PWC [14], but the energy flux propagates in LHM guiding layer in a different way, because the Poynting vector are antiparallel to the wave vector.…”

“…Yet, light must be coupled into LH waveguide in order to investigate experimentally the guided modes. It is known that prism waveguide coupler (PWC) [11] is a convenient coupling method, which has been widely used to various applications, including measuring optical parameters [12], sensing [13] and light modulating [14]. In this work, we discuss prism LH waveguide coupler (PLHWC) where the guiding layer is LHMM.…”

We discuss the prism waveguide coupler where the guiding layer is left-handed metamaterial. The reflection coefficient of this system is obtained, and the reflection spectroscopy takes on a series of reflection dips, which demonstrate that incident lights are coupled into the left-handed waveguide effectively. It is shown that the reflected beam undergoes a lateral shift which can be both positive and negative, depending on the thickness of the coupling layer.

The temperature-dependent reflection spectrums of ultrahigh order guided modes of symmetrical metal-cladding waveguide (SMCW) are measured in angular interrogation. The results show that the reflection spectrum is characterized by extremely narrow resonance dip, which agrees well with numerical calculation. Based on the falling or rising edge of resonance dip of ultrahigh order guided modes of SMCW, a temperature sensor with characteristic of high sensitivity is proposed. Meanwhile, by experimentally determine the linear character between the shift of resonance angle and the variation of temperature, a method of angle compensation is put forward to extend the sensing range. Owing to its characteristics of high sensitivity, low cost and easy fabrication, the temperature sensor based on SMCW will be a promising sensor in many fields.

“…In such configurations, a sudden drawdown in the reflectance on the prism base is caused by the drastic coupling of incident waves into surface plasmon polariton modes in a thin metal layer, and hence the intensity of a p-polarized (TM) reflected wave exhibits a sharp dip when the angle of incidence at the prism base is larger than the totalreflection critical angle [13]. The ATR technique has been a powerful tool for determining metal characteristics (e.g., dielectric function and film thickness) [12][13][14][15], and the surface plasmon resonance (SPR) involved in has become a fundamental mechanism of many optical devices (e.g., optical sensors and modulators [16,17]) and biomolecular sensors [18].…”

Abstract-An EIT (electromagnetically induced transparency)-based prism coupler is suggested for realizing tunable reflection spectrum via quantum coherence of phases in a multilevel system, where destructive and constructive quantum interference will occur among multilevel transition pathways that are driven by two external control fields. In this prism coupler, a semiconductor-quantum-dot (SQD) medium layer, which can exhibit EIT and relevant quantum coherent effects, bounds the prism base, and the two external control fields are used to manipulate the probe field and the excited surface plasmon wave (on the SQD layer surface). Then the surface plasmon wave modes, which are generated by the probe field incident into this multilevel SQD medium layer, can be coherently tunable through the switchable quantum interference (destructive and constructive quantum interference) among the energy levels in the SQD systems. Such switchable quantum interference can be realized if we tune the intensities (i.e., adjust a proper intensity ratio) of the two control fields that drive the SQD multilevel EIT system. New switchable photonic devices, which could find applications in photonic microcircuits as well as some areas in integrated optical circuits, could be designed based on this quantum-interference switchable surface plasmon resonance.
