“…In [38], the V π was demonstrated to be as low as 3.1 V at a high data rate up to 30 Gb/s and 40-50 Gb/s modulations for shorter devices with higher V π were also demonstrated. The achieved V π is close to that demonstrated for LiNbO 3 and InP modulators, however, the insertion loss is relatively high due to free carrier induced loss from pn junctions. In [41], the modulation chirp and dispersion tolerance of this type of modulators were presented.…”

“…The tight bends result in extremely compact optical components and hence flexible circuit design, which are crucial for very large-scale photonic integration. Due to the high index contrast, silicon waveguides can also expand the mode sizes to a few microns to match the mode of optical fibers by shrinking the core size, usually called inverse tapers [3][4][5]. Compact grating structures which can efficiently couple the light between silicon waveguide guiding modes to out-of-plane fiber modes, are also enabled by the high index contrast [6][7][8][9].…”

“…Another approach presented in the literature is to use a spot size converter to transform the SOI waveguide mode to a polymer waveguide mode which matches a lensed fiber mode, as shown in Fig. 1 [3], [4]. The optical bandwidth is typically very large ( 100 nm) and efficiencies are high ( 1-dB loss).…”

“…Actually, no experimental results have been reported in literature. A more elegant solution which is planar geometry is a planar single stage inverted taper [55] (Fig. 2.14(b)).…”

“…In this case, minimum coupling loss lower than 1 dB can be obtained. One of the pioneer inverted taper presented in literature is found in [55]. They demonstrate less than 1dB coupling loss from 0.3 μm × 0.3 μm square silicon waveguides to singlemode fibers with 4.3 μm MFD for the TE mode, for an inverted taper length of 200μm, and using a polymer fiber-adapted waveguide on top of the inverted taper with cross-section dimensions 3μm × 3μm.…”
