HYTS-ATS EDFA automatic test system is a precise, automated platform for fiber amplifiers. It automatically measures spectra, optical signal-to-noise ratio(OSNR), noise figure(NF), input/output optical power, and total power consumption. Integration with environmental-test equipment such as temperature chambers provides combined temperature/performance testing. Host software centrally controls optical switches, instruments, and chambers for efficient batch testing of single-channel or multichannel amplifiers, with channel expansion through optical switches. It supports high-reliability, high-consistency verification of aerospace products.

The SOA semiconductor optical amplifier uses a high-performance InGaAsP/InP gain chip for high-power C-band amplification. An integrated isolator and TEC cooling provide stable polarization-maintaining output. A dedicated drive circuit supports CW and pulsed modes. CW saturated output power is ＞100mW; pulsed operation offers widths down to 10ns and repetition rates up to 1MHz. Stable construction, mature processes, and volume production provide output insensitive to vibration and temperature changes for demanding environments.

Efficient all-fiber amplification around 2800nm. The Amp 2800 mid-IR ultrafast fiber amplifier is a commercial erbium-doped fluoride-fiber amplifier with gain near 2800nm. Amp 2800 delivers watt-level power, diffraction-limited quality, and optical coupling efficiency above 20%, ideal for generating or amplifying mid-IR light. It supports mid-IR solid-state and semiconductor amplification, supercontinuum generation, and tunable ultrashort-pulse amplification. With ultrafast pumping, it generates watt-level tunable ultrafast output or high-energy supercontinuum spanning 2.6 to 4.2 µm. Strong gain near 3μm supports operation from CW to femtosecond pulses. Application example: mid-IR ultrafast amplifier and spectral converter.

Our single-frequency fiber amplifiers provide gain over broad wavelength ranges while preserving narrowband single-frequency signals. Optimized for high output from narrowband sources, they avoid triggering stimulated Brillouin scattering (SBS). They can work with second-harmonic generation (SHG) modules to efficiently convert NIR to visible light.
