  We demonstrate two types of waveguide structures which optically confine
exciton- polaritons in two dimensions and act as polaritonic channels. We show
a strong optical confinement in an etched rectangular waveguide, that
significantly increases the propa- gation distance of the polaritons and allow
to direct them in curved trajectories. Also, we show low-loss optical guiding
over a record-high of hundreds of microns which is com- bined seamlessly with
electrical control of the polaritons, in a strip waveguide formed by
electrically conductive and optically transparent strips deposited on top of a
planar waveguide. Both structures are scalable and easy to fabricate and offer
new possibilities for designing complex polaritonic devices.
