Designed for 1550 nm infrared purposes affords as much as 12x larger sensitivity, quicker response instances, and improved thermal efficiency—excellent for high-speed optical communications, OTDR, and LiDAR.
Phlux Expertise has expanded its line of high-performance infrared sensors with the discharge of a brand new 30 µm avalanche photodiode (APD) below its Aura collection. Designed for 1550 nm infrared purposes, this compact sensor delivers distinctive velocity and sensitivity, making it well-suited for demanding optical programs.
Becoming a member of the prevailing 80 µm and 200 µm fashions, the brand new 30 µm model affords considerably lowered capacitance—between 0.15 and 0.4 pF—enabling a excessive cut-off frequency of as much as 3.5 GHz. This efficiency enhance makes it excellent for ultra-fast, precision duties like gigabit-rate optical communications (together with free-space setups) and optical time area reflectometry (OTDR).
The important thing options are:
- Improved sensitivity extends system vary by as much as 50%.
- Alternatively, permits for lowered laser energy, reducing system prices by as much as 40%.
- Permits dimension and weight discount of as much as 30%.
- Operates reliably at temperatures as much as +85 °C with minimal efficiency degradation.
- Meets MIL-STD-883 and Telcordia GR-468 compliance requirements.
Because of its proprietary Noiseless InGaAs design, the 30 µm Aura APD achieves an extra noise issue of lower than 3.5 at a acquire of 100 and maintains a really low darkish present. Sensitivity is 12 instances larger than customary InGaAs APDs. The sensor has a spectral noise present of simply 260 pA/√Hz at a acquire of fifty, which corresponds to five.2 fW/√Hz at R = 1.0 A/W. With a broad dynamic vary and compatibility with diversified pulse widths, the machine enhances testing capabilities for longer or extra lossy fiber hyperlinks. Floor-mount, TO-packaged, and bare-die choices shall be obtainable.
The brand new 30 µm APD sensor is ideally suited to a spread of superior optical purposes, together with Optical Time Area Reflectometry (OTDR), the place its quick restoration and excessive sensitivity improve accuracy and scale back useless zones. It additionally helps high-speed Free Area Communication and Fiber Sensing programs, providing dependable efficiency in difficult environments. Moreover, its capacity to increase system vary makes it a robust match for Prolonged Vary Telecom purposes, enabling longer-distance knowledge transmission with lowered energy necessities.
CEO Ben White famous rising demand for high-speed APDs throughout communications, testing, and LiDAR purposes, stating, “This growth offers our prospects the pliability to match the suitable efficiency stage to their system necessities, whereas making certain top-tier sensitivity and reliability.”
