Narrow-linewidth semiconductor lasers, micro-optics, silicon photonics (SiP), low noise electronics and high-density packaging are key elements for the development of compact high-end light sources for sensing. A laser module for the interrogation of an RFOG (Resonant Fiber-Optic Gyroscope) includes three distributed feedback …

Radio-frequency (RF) photonics is demonstrating superior performance in communication systems using discrete components. As systems establish an upgrade path balancing challenging bandwidth requirements with size, weight, and power constraints, the time is ripe for transition to a more efficient and cost-effective hybrid …

A compact three-laser source for optical sensing is presented. It is based on a low-noise implementation of the Pound-Drever-Hall method and comprises high-bandwidth optical phase-locked loops. The outputs from three semiconductor distributed feedback lasers, mounted on thermo-electric coolers (TEC), are coupled with …

This paper proposes a novel method to design and manufacture skid-type landing gear cross tubes for light helicopter using Tube Hydroforming (THF). Hydroforming is a promising alternative to conventional fabrication methods, with the potential of reducing costs, weight and environmental footprint by …
