    Information encoding on optical signals is widespread in nowadays technology, ranging from optical fiber links in consumer electronic devices to long-distance communications via fiber networks and biological optical sensing. In many of such diverse applications, the adoption of an integrated-waveguide platform is essential to achieve device miniaturization and to scale-up complexity. Additionally, achieving both rapid and low-loss modulation of the optical phase or intensity is of utmost importance to increase system efficiency or enhance sensitivity. These aspects will also be indispensable to enable the transition to a quantum advantage regime [1], through the use of non-classical states of light, which may be particularly fragile

    Femtosecond laser micromachining is becoming an established technique for the fabrication of complex three-dimensional structures in glass. The combination of laser writing and chemical etching increases the technique versatility by allowing the fabrication of hollow structures within the bulk material. The possibility to encompass both optical and fluidic components in a single substrate allows us to realize optofluidic devices usable in several application fields. Here, we present new investigations of laser-assisted etching in Eagle XG glass showing good etching conditions at low repetition rates, where thermal effects can be neglected, and low irradiation speeds, which allow for complex microchannel network formation

    Integrated photonics is playing an always-increasing role in the development of new technologies and devices, with applications in the fields of optical communications and, more recently, in linear-optical quantum computing and simulations. Actually, the possibility of integrating complex and reconfigurable functionalities inside a small chip allows to develop ultra-stable platforms for the large-scale processing of classical and quantum optical signals [1] , [2]

    A simple technique for procuring liver allografts while protecting arterial vessels

    Arterial injury remains a common complication during organ procurement, with negative effects on postoperative morbidity and graft survival. We describe a simple technique that helps surgeons avoid vascular injuries during isolated liver procurement (without pancreas). This simple technique has been used in 200 liver procurements without any arterial injuries
