ABSTRACTThe realization of single-mode rib-waveguides with dimensions of several micrometers in Silicon-On-Insulator (SOI) is reported. The predicted monomode behaviour is confirmed by comparison of a simulated and a measured nearfield intensity distribution. Waveguide losses below 0.5dB/cm were obtained at wavelengths of 1.3μm and 1.55μm, respectively, independent of the polarization state.

This paper reports on the design and fabrication of Poly(dimethylsiloxane) (PDMS) single mode rib waveguide. PDMS was chosen as the base material for both the core and cladding of the waveguide. Such a PDMS waveguide allows an easy integration with microoptical components for lab-on-a-chip systems fabricated by soft lithography fabrication methods. The modification of the PDMS refractive index was achieved by diluting the base material with hexane. The fabricated PDMS rib waveguides were characterized for mode profile characteristics and the results confirmed the excitation of the waveguide's fundamental mode. The propagation loss was characterized at a wavelength of 635 nm and found to be 0.48 dB/cm. Such a low loss waveguide is useful as basic building block for complex microphonotnics device.

AbstractOptical-fiber-based, hollow-core waveguides (HCWs) have opened up many new applications in laser surgery, gas sensors, and non-linear optics. Chip-scale HCWs are desirable because they are compact, light-weight and can be integrated with other devices into systems-on-a-chip. However, their progress has been hindered by the lack of a low loss waveguide architecture. Here, a completely new waveguiding concept is demonstrated using two planar, parallel, silicon-on-insulator wafers with high-contrast subwavelength gratings to reflect light in-between. We report a record low optical loss of 0.37 dB/cm for a 9-μm waveguide, mode-matched to a single mode fiber. Two-dimensional light confinement is experimentally realized without sidewalls in the HCWs, which is promising for ultrafast sensing response with nearly instantaneous flow of gases or fluids. This unique waveguide geometry establishes an entirely new scheme for low-cost chip-scale sensor arrays and lab-on-a-chip applications.

In this paper we investigate the most popular silicon waveguide structures in the form of a silicon-on-insulator (SOI) rib waveguide. Single mode and birefringence free conditions in these relatively small waveguides are discussed and the influence of the top oxide cladding stress is analyzed. Field profiles for a wide range of waveguide cross section shapes and dimensions are systematically considered. Design guidelines for this type of SOI waveguides are presented.
