Agiltron has developed new mill-spec fiberoptic components of bendable fiber and multi-channel fiber joint. Agiltron is near production of a new class of multimode fiber that is more durable and bendable yet less cost to replace the current mil-spec qualified fibers used in aerospace. We have demonstrated 100 times lower in bending loss than current fibers, little distortion to data transmission, can be spliced and butt connected to conventional fibers with little loss, can withstand extreme fatigue and stress corrosion factor. Agiltron has also produced a 4 channel miniature and ultra reliable 4-channel fiberoptic rotary joint (FORJ).

Optical methods provide a sensitive method for measuring water and microbe contamination levels in jet fuels. Dispersed water in fuel has been measured to below the critical 30ppm level. The optical interface enables electronic recording to be remote from the fuel and hence reduce explosion risk.

We have demonstrated 22 GHz bandwidth dual photodiodes having high amplitude & phase linearity as well as high power handling in both CW and pulsed operation. The two photodiodes are also well-matched in linear as well as nonlinear performance.

Tactical free-space optical communications can add a significant capability to Naval missions, from high bandwidth to operation in RF denied environments. Additionally, a retro-reflective transmission mode holds promise to significantly reduce size, weight, power and cost for disadvantaged platforms.

This paper provides an update on research and development within the Australian defence industry of microwave photonics systems and their application to electronic warfare (EW) receivers. The major developments have diverged into two primary streams: the development of EW receivers to accommodate the signal transmission characteristics of microwave photonic links and development of broadband optical signal processing components.

The PC and PC-NC termini studied here showed tolerable changes in optical transmittance under temperature cycling, vibration testing or mating/de-mating cycles with periodic cleaning. The flat-NC termini studied here showed much greater average change, and much greater variability, from all stimuli than the other types. We hypothesize that this is due to variation in fiber height, and was in contrast to expected variations fiber height for the PC-NC termini as well. There are substantial differences between the designs of the PC-NC and the flat-NC termini which could cause the discrepancy: 1) end face shape, 2) very short fiber attachment region inside the flat-NC terminus, 3) possible inconsistent fiber coating adhesion, or 4) stress caused from use of tight buffered cable with the flat-NC terminus. Failure analysis did not detect epoxy failure. The mate/demate test results highlight the importance of regular cleaning to prevent end face damage.

This work demonstrates a 1000°C capable fiber optic (Wave-Phire™) sensor for gas turbine engine control and health monitoring. This fiber optic pressure sensor can be further developed for flight applications and is amenable to miniaturized (integrated optic) interrogation. The sensing and interrogation technology are both suitable for wide application beyond the engines in other parts of the aircraft, even when high temperatures are not required.

The increased usage of fiber optics technology on aerospace platforms has created greater awareness of the benefits gained by creating or updating standards for aerospace applications. For the past several years ARINC, SAE, ASD-STAN and the DoD have worked fast and hard to fill a variety of standards gaps encompassing a wide range of fiber optic components and design process applications including optical fiber, connectors, cables, termini, splices, cable assemblies, link power budget methodology and margin specification, education and training awareness, cable assembly insertion and return loss measurements, connector inspection criteria and cable harness installation, to name a few. A new initiative underway within JEDEC is working to standardize active and passive components including transmitters, receivers, switches and filters.

We describe the use of swept-wavelength interferometry (sometimes referred to as optical frequency domain reflectometry, OFDR) for high speed, distributed fiber-optic sensing. The technique utilizes continuous gratings written in single mode fiber facilitating high density distributed measurements of temperature or strain up 1 millimeter resolution. The technology used herein is capable of strain measurement rates of up to 1 KHz over the measurement domain with millimeter resolution. This technique shows great utility as a method for dynamic structural health monitoring, model simulation validation for mechanical prototypes, vibration monitoring or closed loop feedback control for process optimization.
