“…The resulting IL of 1.9 dB at a wavelength of 1538 nm consists of two times the excess loss of the mode converters and the waveguide and taper losses. Assuming small waveguide and taper losses, the measurement is in good accordance to the simulation of the excess loss of mode conversion in [ 12 ], which results in 0.9 dB at 1550 nm.…”

“…Twomode excitation is achieved by using mode converters, which can be realized e.g. by laterally shifted tapers (Hoppe et al, 2017a) as depicted in Fig. 1b, by lateral shifted waveguides (Liu et al, 2014), by waveguide steps (Zinoviev et al, 2011), by waveguide gratings (Bruck and Hainberger, 2014) or even simpler by a lateral shift of the external fibers with respect to the center of the grating couplers.…”

“…Using the last approach, at a special fiber position, the first and second order modes are excited in the following dual-mode waveguide with the same power resulting in a balanced excitation (Hoppe et al, 2015). However, imbalanced excitation can also be beneficial if the two modes suffer from different losses because it can increase the extinction ratio (Hoppe et al, 2017a). Similarly, the two modes are combined at the end of the waveguide by the reverse process using a second mode converter, which includes a single mode output.…”
