In fact, slot waveguides have become the key element in order to implement organic materials into silicon photonics. Beside the strip and slot waveguide, the strip-loaded slot waveguide is utilized in this work. The cross section of each waveguide type is shown in Figure 1. All-optical high-speed signal processing with silicon ... a, SEM image of the cross-section of the vapour-deposited organic film covering the silicon waveguide.The ability of the organic material to homogeneously fill the slot between the waveguides is a ... All-optical high-speed signal processing with silicon ... of 1.2+0.1 ns. Although bare silicon strip waveguides can exhibit strong nonlinearities14,17 (g.100,000 W21 km21), free-carrier dynamics on this timescale lead to severe pattern effects in high-speed signal processing. Finally, to prove the viability of SOH slot waveguides for all-optical processing of broadband telecommunication signals by

Waveguides 13 oriented along the (11-2) direction on the Si (110) plane were first fabricated by a standard e-beam

Potential of slot waveguides for silicon-based optical interconnects Yehea Ismail, Hosam Mekawey, Rania Gamal and Mohamed A. Swillam Compact dielectric and plasmonic slot waveguides have low loss characteristics and can be fabricated in a CMOS-compatible manner, and are thus suitable for integration in modern integrated circuits. PHOTONIC STRUCTURES BASED ON SLOT WAVEGUIDES FOR NANOSENSORS:...

Interferometer (MZI), with slot photonic crystal waveguides (PCWs) incorporated in both the arms, as shown in Fig. 1 (a). We start with a silicon-on-insulator (SOI) substrate with 250nm-thick top silicon and 3µm-thick buried oxide (BOX) layers. The slot and holes of the PCWs are filled with an EO

Nonlinear losses of highly nonlinear silicon/organic photonics slot waveguides are analyzed. Unlike silicon strip waveguides, slot waveguides do not show absorption related speed limitations up to highest input powers. Introduction Highly nonlinear waveguides are key components for all-optical on-chip processing at highest bit rates. Of Slot-waveguide - Wikipedia The slot-waveguide was born in 2003 as an unexpected outcome of theoretical studies on metal-oxide-semiconductor (MOS) electro-optic modulation in high-confinement silicon photonic waveguides by Vilson Rosa de Almeida and Carlos Angulo Barrios, then a Ph.D. student and a Postdoctoral Associate, respectively, at Cornell University.

Silicon CMOS compatible transition metal oxide technology for boosting highly integrated photonic devices with disruptive performance OSA | Subwavelength grating slot (SWGS) waveguide on silicon We present a subwavelength grating slot (SWGS) waveguide on silicon platform. The SWGS waveguide is characterized by the merging of a slot structure and a subwavelength grating (SWG) structure. OSA | Increasing the bandwidth of slow light in fishbone-like Slow light, a technology to control the optical signal by reducing the group velocity, has been widely studied to obtain enhanced nonlinearities and increased phase shifts owing to its promoting of the light–matter interaction ability.
