Optical Vector Analyser & Optical Spectrum Analyser

Description

Supply & Installation of an Optical Vector Analyser & Optical Spectrum Analyser. The LUNA OVA 5100 is the only optical vector analyzer (OVA) that would be identified that is capable of acquiring the full Jones' matrix. This enables comprehensive characterisation of passive photonic devices, including polarisation, group delay, and phase, which are essential for optimising optical buffers, delay lines, frequency combs, and microwave photonic filters. No alternative system identified provides LUNA OVA 5100's level of accuracy and measurement speed for full vector characterisation, making it the only viable choice to support SNAP-based microresonator research and maintain Aston University's leadership in photonic device development and characterisation. A sole supplier certificate for the LUNA has been provided by Lambda Photometrics Limited regarding UK distribution. When evaluating high-resolution optical spectrum analysers (OSAs) suitable for our microphotonic device fabrication and sensing applications, The APEX OSA-AP6 provides 0.04 pm (5 MHz) resolution. This level of precision is critical for tuning and characterizing high-Q microresonators and optical frequency combs. APEX also features a higher close-in dynamic range than other options considered, which improves measurement accuracy when analysing closely spaced spectral components. The APEX OSA-AP6 has a sweep speed of up to 35 nm/s, making it significantly faster than other options considered, essential for real-time spectral analysis of fast-changing optical signals, particularly in optofluidic sensing and microwave photonics applications. The APEX OSA-AP6 uses a rectangular-shape resolution filter, which provides a more uniform spectral response, improving measurement stability for broadband and high-Q optical components. Since SNAP technology demands extremely precise spectral characterization, which lower-resolution devices cannot achieve, the APEX OSA-AP6 is the only viable option identified for advancing our research. With its improved measurement method and faster sweep speed, it ensures the sub-picometre precision, resolution, and functionality essential for SNAP microphotonic research.
