Control over the degrees of freedom of photons in microscopic photonic structures, such as polarization, spatial mode, or orbital angular momentum, is essential for applications, e.g., quantum optical experiments on a chip.
We have recently shown direct laser written polymer waveguides fabricated from a low-fluorescent negative tone photoresist via two-photon lithography [1]. Here, we present an optimization of the waveguide's shape, minimizing losses of the propagating light. Further, we report on the current status of structures enabling manipulation of the guided light's polarization in our waveguides.
Our work opens the door to control over photonic degrees of freedom in micro-optical networks for quantum optical experiments and coupling to individual nanoemitters on photonic chips.
