Method and apparatus for optical mode division multiplexing and demultiplexing
TL;DR: In this paper, a method of mode selective coupling or mode multiplexing between integrated multimode (600) and single mode (602) waveguides is proposed. But it is not suitable for single-input single-out (SISO) applications.

Studies on coupling of optical power in fiber to semiconductor waveguide at wavelength 1550 nm for photonics integrated circuits
TL;DR: In this paper, the coupling efficiency between a single mode optical fiber and a three layer semiconductor waveguide was investigated at the optical communication wavelength of 1550 nm. And the upshot of above research asserted overall coupling efficiency of 93.68% and polarisation dependent loss of −7.36 dB can be achieved for the recommended structure at the aforementioned wavelength.
