… We demonstrate a compact silicon polarization beam splitter (PBS) … width variation, and
the polarization extinction ratios remain higher than 20 dB for both polarizations when the width …

… Numerical simulations show that the present PBS has a good fabrication tolerance for the
variation of the waveguide width (more than ±20nm) and a broad band (~50nm) for an …

… We demonstrate a compactly integrated polarization beam splitter (PBS… The optimum
dimension of the bridge waveguide is … for a fixed waveguide width of the bar and cross …

… We included both the nominal design and biased structures with waveguide width variations
of ±25 nm, allowing us to determine the tolerance to fabrication errors. One output of each …

… An inverted taper coupler with a minimum waveguide width of 180 nm was used here for
light coupling with a … The fabricated waveguide width was close to the designed parameter. …

… the excess losses when the waveguide width has some deviation Δ w . Here we assume
that the input/output waveguides and the MMI section have the same width variation Δ w due to …

… Meanwhile, the highest value of excitation coefficient for TE2 mode is generated as the
multimode waveguide width is 0.83 μm. During our calculations, a relatively weak interference …

… results are not ideal which may mainly results from following reasons: (1) the fabrication
errors of the waveguide, including the waveguide width errors and the roughness of the …

… Here we assume that the two waveguides of the asymmetric coupler have the same width
variation Δ w due to the fabrication error [5]. From Figs. 7(a) and 7(b), it can be seen that the …

… We use the width of the Gaussian fit to determine the rms transverse velocity to be v t = 17.2
± 3.5 cm / s . The dip in flux near 6 mm is an artifact that is due to the presence of some stray …
