Introduction: There is currently significant interest in all-ceramic dental restorations. A potential non-metallic material for such restorations is an apatite-mullite glass-ceramic that could be processed to shape using different processing techniques. The aim of this study was to assess and evaluate the ability of an apatite-mullite glass-ceramic material to be processed using three routes: l...

Laser Direct Writing (LDW), also known as 3D multi-photon laser lithography of resins, is a promising technique for fabricating complex free-form elements, including micro-optical functional components. Regular organic or hybrid (organic–inorganic) resins are often used, with the latter exhibiting better optical characteristics, well having option to be heat-treated into inorganic glass-like st...

Solution-processing of chalcogenide glass materials has many benefits for the fabrication of photonic devices. We report on the structural properties of Ge23Sb7S70 glass during solution-processing. The molecular and micro-structure of the bulk glass and the n-propylamine solution, as well as the spincoated thin films and post-irradiated films are analyzed by Raman spectroscopy, scanning electro...

We have applied the sol-gel process to generate optical microstructures in glass using in-house developed sol-gel materials. The synthesis of our sol-gel glass materials is based on the formation of particles of controlled size from organo-metallic compounds. The overall shrinkage during annealing of the gel material is negligible and does not imply crack formation. Silica, titania and binar y ...

Demand for high integration of optoelectronic and micro-optical components into micro-electronic systems communication, computing, medical, sensing applications is increasing. Advanced hybrid packaging technologies are used to enhance glass-based substrates featuring electrical, thermal, optical functionalities with laser diodes, modulators, isolators, photonic integrated circuits (PIC), beam-s...

Conventional material removal of BK7 optical glass will normally result in brittle fracture at the surface, generating severe subsurface damage and poor surface finish. Subsurface damages induced by grinding strongly influence the mechanical strength and optical quality of optical glasses. However, through ductile mode grinding it is possible to reduce the surface and subsurface cracks. It is m...

A novel valveless micro impedance pump is proposed and analyzed in this study. The pump is constructed of a upper glass plate, two glass tubes, a PDMS (polydimethylsilxane) diaphragm with an electromagnetic actuating mechanism and a glass substrate. The actuating mechanism comprises an electroplated permanent magnet mounted on a flexible PDMS diaphragm and electroplated Cu coils located on a gl...
