Coherent Optical Receiver (CORX) for Defence & Secure Communication

The CORX Coherent Optical Receiver from ID Photonics is designed for advanced optical communication research, receiver characterization, and secure communication applications in defence and aerospace environments. Modern defence communication systems increasingly require high-capacity optical links, advanced modulation formats, reliable signal detection, and efficient use of available optical bandwidth. The CORX provides a reference-grade coherent receiver platform that enables researchers and engineers to evaluate optical signals and receiver performance during the development of secure communication systems. It can be used for defence optical communication research, secure link validation, coherent receiver testing, RFoG research, and terahertz communication development. By providing coherent detection capabilities, the CORX enables receiver-side analysis of advanced optical communication signals before they are integrated into complete communication architectures. This makes it suitable for defence laboratories, photonics research centres, universities, and organizations developing next-generation secure communication technologies.

The CORX can be used to characterize advanced optical modulation formats such as DP-QPSK and higher-order QAM, which are important technologies for achieving high-capacity optical transmission and improved spectral efficiency. Researchers can combine the receiver with suitable optical transmitters, signal generators, and narrow-linewidth tunable laser sources to create a complete coherent optical communication test setup. For example, the CORX can be paired with the OMFT IQ Reference Transmitter for generating compatible test signals, while a narrow-linewidth tunable laser can be used as a local oscillator reference for phase-sensitive coherent detection. Automatic bias control can also be incorporated into the test configuration to maintain appropriate operating conditions for optical modulators. These capabilities allow engineers to investigate modulation performance, coherent detection, receiver response, and optical link behaviour under controlled laboratory conditions. The CORX is particularly relevant for research involving Radio-over-Fiber (RFoG) and emerging terahertz communication technologies, where optical links can be used to transport high-frequency signals across communication architectures. Accurate receiver characterization is essential for evaluating these technologies and optimizing their performance before system integration or field testing.

For defence and secure communication programs, the CORX Coherent Optical Receiver provides a flexible platform for optical link validation from laboratory research through to field-trial preparation. Engineers can use the receiver to investigate the performance of coherent optical communication links and assess how different transmitters, modulation formats, and optical components perform within a complete test setup. Its configurable bandwidth options allow the receiver configuration to be matched to the requirements of the communication system under development. Applications include secure high-capacity optical links, defence photonics research, coherent receiver characterization, RFoG communication research, terahertz communication development, advanced optical modulation testing, and optical communication link validation. By supporting detailed receiver-side analysis, the CORX helps researchers understand the behaviour of advanced optical signals and develop reliable communication architectures for demanding environments. It can form part of a broader photonics test platform together with reference transmitters, tunable laser sources, modulation control systems, and other optical measurement equipment, providing a practical solution for organizations working on next-generation defence and secure optical communication technologies.
