2000nm 60nm Single Mode Tunable Filter

High-speed tunable bandpass filter. As a two-port optical module, the input port receives broadband multi-wavelength light and only a small portion of the incident signal within the passband is allowed to pass through the filter and directed to the output port. The center wavelength of the selected band can be tuned to anywhere within the operating wavelength range. In our design flexibility, transmission bandwidth, wavelength tuning range can be customized. The voltage-controlled filter requires no moving parts, has fast tuning speed, and is compact and small in size. Our filters are used as suppression filters in optical systems to improve laser signal-to-noise ratio in wavelength scanning engines of optical spectrum analyzers (OSAs) and in system diagnostic communication systems.

1550nm Polarization-Maintaining Fiber Polarization Combiner

The Polarization Beam Splitter (PBS/PBC) is used to couple two orthogonal polarized light beams into a single optical fiber, or to couple the orthogonal polarized light from a single output into two separate optical fibers. It can also be used in reverse to couple two orthogonal polarized light beams from a polarization-maintaining fiber into a single-mode output fiber. These devices are commonly used for power combining in pump lasers, improving the power of fiber lasers.

5nm fused taper ultra-narrowband wavelength division multiplexer 1550/1555nm bandwidth ±0.5nm

Fused taper ultra-narrowband wavelength division multiplexer refers to a one-time taper wavelength division multiplexer with a wavelength interval of 5nm. Fused taper wavelength division multiplexing refers to a technology that transmits multiple wavelength optical signals in one optical fiber at the same time. With the development of optical communication systems, it is widely used in optical fiber sensors, optical fiber lasers, optical fiber amplifiers (EDFA), high-speed multi-wavelength transmission, etc. In the wavelength range, an optical communication system with multiple wavelengths on a pair of optical fibers or a single optical fiber is required, where the interval between each wavelength is 5nm. In this case, the wavelength division multiplexing with a smaller channel interval in the same window is called ultra-narrowband wavelength division multiplexing SUNBWDM, which has low loss, good stable performance, simple maintenance and convenient power supply.

1310nm 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.
