Using photonics technologies to establish communications in air-to-ground, air-to-air, and air-to-space fields offers many advantages related to transmission speed, low Size Weight and Power (SWaP) systems, spectrum regulations, and immunity to electromagnetic interference. Specifically in UAV laser communications, photonics technology has the potential to establish secure and reliable high-speed links that are also immune to jamming/spoofing, where transmissions cannot be detected, in contrast to traditional RF technology. This article discusses the additional advantages of using photonics in the design process of UAV laser comms development, and provides an example of a UAV laser transmitter under testing at Gooch & Housego.
To analyze the specific damage characteristics of high-power laser optics, it is important to understand the laser induced damage threshold (LIDT), an analytical threshold determination method that can reveal damage diagnostics, and its testing provides a lower-cost option for coating development.
When designing micromaterial processing equipment, manufacturers need to consider a complex interplay of numerous factors, such as extremely accurate positioning of lasers for cutting, drilling, scribing, or for marking at the highest rate possible. In many integrated circuits, the required beam accuracies can be staggering. For example, processing equipment must be able to drill microvias and scribe trenches less than 10 μm in size. Display manufacturers must also accurately place and repair pixel circuitry at ever shrinking resolutions on increasing larger substrates. This requires advance tooling to avoid significant increases in processing time and costs.
Optical coherence tomography (OCT) can be used in many medical applications including displaying real-time details of eye diseases, detecting skin cancer, or monitoring heart surgery. The OCT market is set to grow even further over the next few years as the efficiency and effectiveness of imaging improves.

The broad emission spectrum of thulium fibers, which can extend from 1600 to 2200 nm, makes a thulium fiber laser an excellent choice for building widely tunable fiber lasers. This paper details Gooch & Housego's results testing an all-fiber thulium laser system that can be tuned to any wavelength between 1710 to 2110 nm, without using any moving mechanical parts.
The ISLA project was a research and development project with the goal of developing “building block” components of compatible and self-consistent active and passive fibers, fused fiber couplers and combiners, fiber-coupled isolators, modulators and high power pump laser diodes. This project also intended to develop a CW, a pulsed and a short pulse laser demonstration laser for use in applications testing. This paper delivers an overview of the project, the results from Gooch & Housego’s work on developing passive components for 2 µm fiber lasers, and the research efforts on different isolator materials with the largest Verdet constants to be used in 2 µm isolators.
Increasing use of fiber lasers and fused fiber technology for industrial, medical, and sensing applications has led to the development of fused fiber devices in all-fiber system architectures. This article demonstrates Gooch & Housego’s efforts developing single-mode fused couplers in a ZBLAN fiber in the mid-IR range.
Fiber lasers operating in the 2 µm region with a large mode area in an “eye safe” region of the spectrum are attractive to many applications such as laser machining and biomedical systems. Gooch & Housego has made recent developments in acousto-optic modulators and tunable filters that are specifically optimized for fiber systems operating at or around 2 µm. This article discusses the important consideration of the choice of interaction medium, such as acousto-optic devices, especially for the polarization behavior of the device when used in a fiber system.
Acousto-optical tunable filter (AOTF) technology is growing to replace conventional and cumbersome mechanical techniques within biomedical applications for confocal microscopy. Benefits of using AO tunable systems include electronic control, configurable drivers for improving operator flexibility, feedback stabilizing systems to maintain wavelength stability for all environmental conditions, and custom-grown tellurium dioxide crystals to ensure optimal performance. This article discusses the evolution of confocal microscopy in using AOTF technologies, as well as maximizing the potential of AOTF systems and their benefits to users by integrating next-generation drivers.
The current pace of Gooch & Housego's development of affordable high performance SWIR cameras does not match their pace of developing affordable high performance SWIR lenses. As a result, lower image quality is more likely to stem from the lens rather than the camera. This article discusses the technical challenges of creating compatible lenses that deliver high image quality and transmission across the full extent of the SWIR band at a much cheaper cost.
Gooch & Housego's (G&H) approach to high-reliability (HI-REL) fiber coupler manufacturing has been further developed by balancing the attention to detail with their rapid changes in their response to market. At G&H’s Torquay facility, they recently had to triple the output of couplers for prestigious clients while maintaining their high quality standards. To meet this demand, G&H needed to make a shift in their testing and manufacturing processes. This blog article describes this delivery milestone, as well as the efforts put into it, and further plans for product development.
Many hyperspectral imaging (HSi) systems use a diffraction grating to split up a line of an image into strips with different wavelengths and so build up a 3D image cube. While this push-broom process works well for capturing hyperspectral images where there is a built-in, one-dimensional relative movement between the camera and the object, there are many situations where band sequential imagers are more effective. This article explores the basics of acousto-optic tunable filter (AOTF) and polarimetric technology and discusses the advantages of using those approaches for hyperspectral imaging. By Alexandre Y. Fong and Jon Ward, Gooch & Housego
