III/V semiconductors exhibit high carrier mobility, facilitating high-frequency operations. By combining the photodiode based on these semiconductors with silicon nitride (Si3N4) waveguide, a groundbreaking platform for photonic integrated circuits can be fabricated. This integration allows the superior electronic properties of III/V materials with the robust waveguide, enabling high frequency operation. In this paper, we present a detailed procedure for the integration of III-V optoelectronics with Si3N4 waveguides using the micro-transfer printing.

Post-fabrication rectangular waveguides are required to be tested for their satisfactory electrical performance. Possible causes and mitigation is discussed in detail in this paper. Simulation and measured results for the WR-28 reference waveguides are presented. For the correction in electrical response deviation in fabricated waveguide Dent tuning of the waveguide has been explored. WR-28 waveguide performance is measured and dent tuning is attempted for the waveguide pieces. Time domain reflectometry is used for the determination of the discontinuities causing significant reflections.

Flexible organic single crystals are evolving as new materials for optical waveguides that can be used for transfer of information in organic optoelectronic microcircuits. Integration in microelectronics of such crystalline waveguides requires downsizing and precise spatial control over their shape and size at the microscale, however that currently is not possible due to difficulties with manipulation of these small, brittle objects that are prone to cracking and disintegration. Here we demonstrate that atomic force microscopy (AFM) can be used to reshape, resize and relocate single-crystal microwaveguides in order to attain spatial control over their light output. Using an AFM cantilever tip, mechanically compliant acicular microcrystals of three N-benzylideneanilines were bent to an arbitrary angle, sliced out from a bundle into individual crystals, cut into shorter crystals of arbitrary length, and moved across and above a solid surface. When excited by using laser light, such bent microcrystals act as active optical microwaveguides that transduce their fluorescence, with the total intensity of transduced light being dependent on the optical path length. This micromanipulation of the crystal waveguides using AFM is non-invasive, and after bending their emissive spectral output remains unaltered. The approach reported here effectively overcomes the difficulties that are commonly encountered with reshaping and positioning of small delicate objects (the "thick fingers" problem), and can be applied to mechanically reconfigure organic optical waveguides in order to attain spatial control over their output in two and three dimensions in optical microcircuits.
