Fabrication of aluminium airbridges for microwave interconnects on lithium niobate on Damascene silicon nitride photonic chips

Here we discuss the wafer-scale fabrication process flow of aluminium airbridges for microwave (MW) interconnects on lithium niobate on Damascene silicon nitride (LNOD) photonic chips. We also discuss the subsequent chip release procedure that preserves the bridges allowing for safe release of these delicate structures.

On the fabrication of high-surface-area and high-aspect-ratio gold nanostructures

We highlight some stability issues in high-surface-area and high-aspect ratio gold nanostructures fabricated using inorganic adhesion layers on silica substrates. We ascribe these problems to capillary and surface effects and show the use of organic silane self-assembled monolayers to improve the long-term stability of such structures.

Transition metal dichalcogenide metamaterials with atomic precision

Here we will discuss our novel anisotropic wet-etching method that allows scalable fabrication of TMD metamaterials with atomic precision, combined with traditional nanolithography techniques.[1] We show that TMDs can be etched along certain crystallographic axes, such that the obtained edges are atomically sharp and exclusively zigzag-terminated. This allows us to fabricate interesting hexagonal nanostructures of predefined order and complexity, including a few nanometer thin nanoribbons and nanojunctions.

Fabrication of patterned silicon nitride nanomembranes at the LKB

Thin silicon nitride nanomembranes are attracting growing attention following a novel fabrication method which consists in patterning them with a phononic crystal. In engineering the vibrational mode profile, the dominant mechanisms of loss, radiation loss and intrinsic material loss, are simultaneously addressed and mitigated. The fabrication method employed by the optomechanics group at the Laboratoire Kastler Brossel is here presented, only employing basic lithography techniques and wet etching processes.
