The fourth seeded Indian pair, who clinched two titles this year at Brazil and Russia, defeated French pair of Ronan Labar and Audrey Fontaine 21-10 10-21 21-17 in a 44-minute clash to reach the final four.
They will next take on Denmark's Soren Gravholt and Maiken Fruergaard.
However, it was a disappointing day for B Sumeeth Reddy and Meghana Jakkampudi as they lost 7-21 10-21 to seventh seeded German combo of Marvin Emil Seidel and Birgit Michels in another mixed doubles match.
