Abstract

We report on a device capable of generating long optical path differences through the use of a combination of a tunable TE–TM converter and a phase shifter. The values that are achievable (~4 mm) are approximately three times higher than those obtained with integrated imbalanced Mach–Zehnder interferometers, with the additional advantage of low optical losses.
