Due to the increasing trend of photonic device miniaturisation, there is also an increased need for optical splitting in a small volume. We propose a smart solution to split light in three dimensions (3D). A 3D optical splitter based on multimode interference (MMI) for the wavelength of 1550 nm is here designed, simulated, fabricated and optimised for splitting at 1550 nm. We focus also on the possibility of its direct integration on an optical fibre. The design is focused on the use of 3D laser lithography based on the direct laser writing (DLW) process. The output characteristics are investigated by near-field measurement, where we confirm the successful 1 × 4 splitting on a 158 µm long MMI splitter.

Europium Eu -doped deoxyribonucleic acid-cetyltrimethylammonium (DNA-CTMA) biopolymers have been prepared and characterized optically. Quartz capillary tube encapsulated Eu -doped biopolymeric waveguides have been fabricated via a simple withdrawal molding technique. Optical amplification at 612-nm wavelength has been demonstrated in these waveguide devices, and the signal enhancements for different lengths of the devices have been measured. A maximum signal enhancement of 24 dB has been obtained for a 15-mm-long device.
