“…To illustrate this lively, two examples will be presented in this section. One is the famous ultra-fast photo-detector [8] , highlighting SPPs' power to circumvent conventional problems; the other is the optical polarizer of anomalously high performance [19] , emphasizing that to make use of SPPs, one may need to explore unusual conditions under some circumstances.…”

The wide field-of-view (FOV) optical receiver has many advantages in optical wireless communication, sensing and detection. However, the FOV is limited by some tradeoffs of the receiver's components employing conventional optical devices. Furthermore, present mechanisms to extend the FOV are not effective. To realize the wide FOV receiver effectively, we propose surface plasmon polaritons (SPPs) as the potential candidate. Two examples are presented to lively illustrate SPPs' striking power to offer unexpected solutions to conventional problems. It is shown that unusual conditions should be explored to make use of SPPs under some circumstances. Excitations of localized SPPs, which are independent of the incidence angle, are suggested as the mechanism for the wide FOV receiver. Some progress in the optimization of SPPs' excitation at oblique incidence is also reported.wide field-of-view, optical receiver, SPPs, extraordinary optical transmission In optical wireless communication, sensing or detection system, the link design is very important. According to the degree of directionality of the transmitter and receiver, optical wireless links can be classified into three types, directed links, non-directed links and hybrid links [1,2] . Directed links require aiming to establish a link between directional transmitters and receivers. Nondirected links alleviate aiming by using wide-angle transmitters and receivers. Hybrid links combine transmitters and receivers of different degrees of directionality. At present, directed link design has been widely used in most areas such as free-space optical communication (FSO), inter-satellite optical communication, back-scattered laser radars, since it minimizes path loss and maximizes power efficiency.Non-directed links or hybrid links employing wide field-of-view (FOV) receivers, even though having limited applications at present, will be promising in the future. For a wide FOV receiver, optical signals incident from a large range of angles can be accepted and detected, alleviating the need of aiming. Furthermore, if these signals can be received and processed very fast, and no scanning is needed, one can envisage that optical wireless communication, sensing or detection of novel types can be realized. For example, wireless communication between multiple terminals and multiple-objects sensing or detection can be realized. More importantly, the realization of real-time communication with detection of fast moving or even unexpected objects will lead to revolutions. As a result, the present personal radio communication can be extended to the infrared region, sparking optical personal communication of large bandwidth.Wide FOV optical receivers, however, are very difficult to realize. A receiver for free-space signals can be divided into three major parts, the optical filter which filters background noises, the optical system which concentrates the light, and the photo-detector which translates the optical signal into the electrical one. When these components employ present devices, ...

“…To implement these techniques various kind of material are used as specific layers (cladding, buffer) in the waveguide structures [6]. The polarization property which is used in this paper is to selectively attenuate the TE or TM modes of the optical waveguide, resulting in a TM-pass or TE-pass polarizer [7]. Indium-Tin-oxide (ITO), a wide band gap semiconductor which comes under the group of transparent conductive oxides, has been used successfully as an absorbing layer to select a specific polarization [8][9].…”

“…However, this type of polarizer is usually long (~1cm) and the fabrication is relatively complex because an additional thin highindex cladding is needed. Metal is also often used to realize a polarizer because the strong polarization dependence of the plasmonic modes in a metal-dielectric waveguide [4][5][6]. In ref [7], a TE-pass polarizer is presented by utilizing the vertical coupling between short range surface plasmon polariton mode and dielectric waveguide mode.…”

Abstract:A new way to make broadband polarizers on silicon-on-insulator (SOI) waveguides is proposed, analyzed and characterized. The characteristics of the eigenmodes in a shallowly-etched SOI ridge optical waveguide are analyzed by using a full-vectorial finite-different method (FV-FDM) mode solver. The theoretical calculation shows that the loss of TE fundamental mode could be made very low while at the same time the TM fundamental mode has very large leakage loss, which is strongly dependent on the trench width. The leakage loss of the TM fundamental mode changes quasi-periodically as the trench width w tr varies. The formula of the period ∆w tr is given. By utilizing the huge polarization dependent loss of this kind of waveguide, a compact and simple optical polarizer based on a straight waveguide was demonstrated. The polarizer is fabricated on a 700nm-thick SOI wafer and then characterized by using a free-space optical system. The measured extinction ratio is as high as 25dB over a 100nm wavelength range for a 1mm-long polarizer.
