With the gradual advancement of the national marine strategy, the deep-sea applications of optical fiber hydrophones have becoming more and more extensive with higher requirements of the reliability. Based on six basic technology platforms, HYC has launched a series of Michelson interferometers that can be used in deep sea hydrophones. The product line includes FRM (Faraday Rotating Mirror) and Coupler devices featuring ultra-miniaturized packing, ultra-high reliability. It is ideal for fiber optic interferometric sensor systems for deep-sea 5000m signal detection.
Based on basic packaging process and materials technology and glue & stress models technology, the stability of FRM and coupler can be greatly improved. After 48 hours of continuous high-strength hydraulic test (45MPa), pressure fatigue test (low pressure 0MPa ~ high pressure 6.75MPa), 72 hours PCT test (120 ℃, 2 atmospheres, 100% humidity) and a series of mechanical tests, the IL variation of the experimental product is still within 0.5dB.
HYC provides two versions to meet different needs, one is miniaturized + ultra-high reliability version, another is ultra-miniature version. The package sizes of the first miniaturized + ultra-high reliability FRM and coupler are φ3.0x12 mm and φ3.0x40 mm respectively. The package sizes of second ultra-miniature FRM and coupler are φ2.5x12 mm and φ2.5x30 mm respectively, which is ahead of most similar products on the market, and can also meet environmental and mechanical experiments required by Telcordia GR-1209 /1221.
The Michelson Interferometers components provided by HYC not only ensure low loss, ultra-high reliability, and ultra-miniaturization, but also adopt a low-cost strategy to reduce costs through functional integration, and truly providing customers with competitive product solutions.
HYC has always pay high attention to R&D investment and has a professional R&D team, owns a number of domestic and foreign patents and has a comprehensive six core technology platforms.
- Optical design, simulation and ray tracing capability based on Zemax, Matlab and Mathcad;
- Free space optics design, submicron alignment / coupling/assembly capabilities;
