In this work we use a hybrid geometrical and wave-optical approach to design and simulate stacked microlenses with varying fields of view. After 3D printing, an excellent agreement of simulated and measured imaging performance is found.
We describe in detail the manufacturing procedures for selectively closing holes in photonics crystal fibers and their infiltration with different liquids. We apply our method to create a large mode area liquid-filled photonic crystal fiber which consists of 19 liquid strands. By changing the mixing ratio between toluene and ethanol and by varying the temperature, we show continuous tuning from isolated...
