G. Ramantoko et al., SYNTHESIS OF LARGE OPTICAL DELAYS BY MODE-COUPLING IN ELECTROOPTICALLY TUNABLE TE-TM MODE CONVERTERS, Optics letters, 21(6), 1996, pp. 372-374
We report on a device capable of generating long optical path differen
ces through the use of a combination of a tunable TE-TM converter and
a phase shifter. The values that are achievable (similar to 4 mm) are
approximately three times higher than those obtained with integrated i
mbalanced Mach-Zehnder interferometers, with the additional advantage
of low optical losses. (C) 1996 Optical Society of America
