2000nm Single-Mode Fiber Reflector

Examples of fiber total reflection mirrors used in erbium-doped fiber amplifiers. In this application, a fiber-based back reflector is placed at the end of an erbium-doped fiber, reflecting light back into the fiber in the direction of the incident light. A circulator is used to direct both the input and amplified output signals along their respective optical paths. This setup allows the signal light to pass through the gain fiber twice, effectively enhancing the amplifier's gain absorption efficiency. Another practical application of back reflectors is the construction of tunable back reflectors, as shown in Figure 2. Feedback signals from a downstream back reflector can cause instability in certain devices, such as laser diodes. By incorporating a tunable back reflector, the sensitivity of a device to back reflection can be determined. A tunable attenuator enables users to introduce a controlled reflection into the system. By analyzing the effects of back reflection, users can calculate parameters such as noise level, bit error rate, and distortion.

10mm Ge large light sensitive surface detector (BNC interface output)

Germanium photodiodes are often used to measure optical power in the near-infrared range, especially in cost-sensitive applications or where large area detectors are required. However, compared to similarly sized InGaAs detectors, Germanium detectors have lower shunt resistance and higher dark current, resulting in higher overall noise levels. Therefore, Germanium detectors are well suited for applications where the detection signal is much higher than the noise floor. Idealphotonics Photonics offers the "HS" series of Germanium photodiodes with higher than typical shunt resistances for improved performance.
