Slot waveguides for silicon photonics

By Editor

Abstract: A silicon-organic hybrid electro-optic (EO) modulator based on one-dimensional photonic crystal slot waveguides is proposed and demonstrated. Effective EO coefficient up to 490 pm/V is observed as a result of the slow group velocity in the proposed structure.

The polarization rotator is a critical component in silicon photonics to mitigate against undesirable polarization sensitivity. This paper describes an efficient polarization rotator with low insertion loss. The rotator exhibited high extinction ratio (>14 dB) for transverse-magnetic (TM)-transverse electric... Integrated Photonics Laboratory Silicon photonics has become a viable technology platform for realizing compact, power-efficient, CMOS-compatible photonic integrated circuits.Therefore, to increase the light-matter interaction, we embed a layer of graphene in a silicon slot-waveguide structure. Slot-waveguide — Wikipedia Republished // WIKI 2 A slot-waveguide is an optical waveguide that guides strongly confined light in a subwavelength-scale low refractive index region by total internal reflection.^ Schrauwen J., Van Lysebettens J., Vanhoutte M., Van Thourhout D. et al., "Iodine enhanced focused ion beam etching of silicon for photonic...

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 High Performance Optical Modulator Based on Electro-optic 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 Experimental GVD engineering in slow light slot photonic
