“…In practices, a low loss, high extinction ration, and compact footprint polarizer is highly desired. Many designs have been proposed and demonstrated on silicon wafers [68][69][70]. The basic rationale of designing a polarizer is to lose or filter unexpected polarization state out from the optical propagation paths with negligible effect on desired polarization state and maintain the device size as small as possible.…”

One-dimension (1D) photonic crystals have been widely used in silicon photonics due to its simple structure and multiple working regimes: diffraction, Bragg reflection, and subwavelength regimes. Thanks to recent development of photonic technologies and highresolution lithography, many 1D photonic crystal-assisted silicon integrated devices have been proposed and demonstrated to further increase integration density and improve device performance. This chapter first presents some fundamentals of 1D photonic crystals. An overview of the applications of 1D photonic crystals in silicon photonics is then given including grating couplers, waveguide crossings, multimode interference couplers, polarization-independent directional couplers, hybrid lasers, polarizers, and high-order mode filters, among others. Particular attention is paid to providing insight into the design strategies for these devices.

“…In 2012, the polarization-dependence of the mode coupling [84] as well as the mode absorption loss [86] in a silicon hybrid nanoplasmonic waveguide has been utilized to realize compact TE-pass polarizers. For a 30 µm-long polarizer demonstrated, the extinction ratio is~23 dB and the insertion loss is about 2 dB.…”

Recently hybrid plasmonic waveguides have been becoming very attractive as a promising candidate to realize next-generation ultra-dense photonic integrated circuits because of the ability to achieve nano-scale confinement of light and relatively long propagation distance. Furthermore, hybrid plasmonic waveguides also offer a platform to merge photonics and electronics so that one can realize ultra-small optoelectronic integrated circuits (OEICs) for high-speed signal generation, processing as well as detection. In this paper, we gave a review for the progresses on various hybrid plasmonic waveguides as well as ultrasmall functionality devices developed recently.

“…Generally, HPWs have the advantage of the long propagation length compared with DLSPPWs due to their low loss. Therefore, HPWs are used in several applications, such as an optical laser [8], polarization rotators [9,10,11,12], a wavelength filter [13], ring resonators [14,15,16], an optical polarizer [17], a directional coupler [18], a power splitter [19], and polarization splitters [20,21]. Since these plasmonic devices are fabricated on Si substrate together with optical devices based on silicon wire waveguides, the coupling between these two different waveguides are necessary for their integration.…”

We present a photonic-plasmonic mode converter using modecoupling-based polarization rotation for connecting a silicon wire and hybrid plasmonic waveguides on a metal-inserted silicon platform. By using the polarization rotator based on defect-introduced silicon wire waveguide, the proposed mode converter can convert the photonic TE mode into the hybrid plasmonic TM mode. At the beginning, to identify a cross-sectional structure for polarization conversion, we investigate the hybrid parameters that determine the degree of mode rotation using the two-dimensional vector finite element method. Next, using the three-dimensional vector finite element method, we investigate the conversion characteristics of the whole device including input and output ports. Numerical results show that the extinction ratio of 46 dB and the insertion loss of 0.36 dB are achieved. The tolerance of the defect is also numerically evaluated. Our proposed mode converter can reduce insertion losses compared to conventional mode converters based on a taper-introduced butt joint structure.
