Abstract

We demonstrate low-loss asymmetric slot waveguides in silicon-on-insulator (SOI). 130 and 180 nm wide slots were fabricated with a 248 nm stepper, in 200 nm thick silicon. An asymmetric waveguide design is shown to expand the range in which the TE0 mode is guided and suppress the TE1 mode, while still maintaining a sharp concentration of electric field in the center of the slot. Optical propagation losses of 2 dB/cm or less are shown for asymmetric slot waveguides with 130 nm wide slots and 320 and 100 nm wide arms.

Fig. 1
Fig. 1 (a) A Dispersion diagram showing TE0 and TE1 modes for various slot offset amounts of design A. Design A implies a 110 nm slot offset from an initial symmetric design of two 210 nm wide arms and a 130 nm slot resulting in a 130 nm slot with 320 and 100 nm wide arms. The corresponding dispersion curve for design A is shown in red. Adding an offset to the location of the slot extends the guiding range for the TE0 mode greatly, while minimally changing the TE1 cutoff. (b) A similar dispersion diagram for varying degrees of asymmetry of design B (shown in red). (c) A similar dispersion diagram for varying degrees of asymmetry of design C (shown in red).

Fig. 2 (a) Optical mode pattern of reported 130 nm slot waveguide with 320 and 100 nm arm widths (design A). This design implies a slot offset of 110 nm. The electric field intensity, |Ex|, is indicated by the contour colors and is normalized to a total mode power of 1 W. (b) Mode pattern for 130 nm slot with slot offset of 80 nm. (c) Mode pattern for 130 nm slot with slot offset of 50 nm. (d) Mode pattern for 130 nm slot with slot offset of 20 nm. (e) Mode pattern for perfectly symmetric 130 nm slot. χ3 effective area, Aeff, is shown for each geometry.

Fig. 5 (a) Normalized wavelength sweeps of devices of different lengths of design A on chip 1. A quadratic fit is seen with each device used to determine peak optical transmission. The signal-to-noise ratio for the best performing device is 44 dB. (b) Normalized optical power vs. waveguide length for these devices. Error bars show uncertainty of loss due to grating couplers. A linear regression shows 1.7 ± 1.1 dB/cm propagation loss as seen in Table 1. The linear fit falls well within one standard deviation of all of the data points, suggesting our uncertainty estimation may overstate the true level of statistical variation encountered in each measurement. (c) Normalized optical power vs. waveguide length for a single test of design A, chip 2. A linear regression shows 2.9 ± 0.4 dB/cm propagation loss, within one standard deviation of the mean propagation loss of 2.4 ± 0.9 dB/cm shown in Table 1.
