Fiber optic built-in test (BIT) for avionics application has been postulated and researched for several decades [1–3]. Optical time domain reflectometry (OTDR) was demonstrated as a method for a fiber optic transceiver to fault isolate fiber optic cable plant interconnects to ten centimeter resolution [4]. BIT-capable fiber optic transceiver transmitter and receiver signal strength indication was also demonstrated [5]. One centimeter fault isolation resolution was demonstrated by integrating a OTDR application specific integrated circuit within transceiver packages [6–7]. In this paper, we describe the development and demonstration of this technology to determine pass/fail criteria of a fiber optic link.

Photonic ICs (PICs) exhibit insertion losses when connected to an optical fiber with shape/size mismatch. This paper describes the use of 3D laser lithography to print optical microspheres directly on the output facet of rectangular PIC waveguides for connection with a circular optical fiber core.

Barium titanate is a highly desired material for the development of advanced linear phase modulators due to the exceptionally large value of its electro-optic coefficient. While attempts have been made in the past to utilize this material property, the overall device performance has not been as sensitive as expected due to a number of special considerations that were not made as a result of the off-diagonal nature of barium titante's electro-optic coefficient. This work discusses these special considerations, presents an in-house characterization technique that is being developed specific to these off-diagonal coefficients, and demonstrates preliminary device designs for a high-performance barium titanate modulator.

Photonic technologies continue to make tremendous strides as advanced sensors in the automotive, commerce, medical, telecommunications and mil/aerospace markets [1,2,3]. Research and development in photonics is also growing on a global scale and will have an impact on the next of segment of the economic growth integral to advances in 5G and adaptive/reconfigurable mesh information networks [4,5,6]. It is critical to note that to take full advantage of what photonic technologies have to offer, they must achieve higher levels of integration of their key components and further merge efficiently with mainstream semiconductor technologies in order to be most effective as more and more data needs to be represented with very low latency. This paper delves into the trends being established globally in integrated photonics and addresses the some of the challenges required to improve radio frequency (RF) sensing that are likely to be common across mil/aerospace and commercial applications.
