    • 1550nm Phase Modulator 300 MHz

    The PM-1550-300-PA phase modulator is a high-performance LiNbO3 modulator with a bandwidth of up to 300 MHz. This modulator provides phase modulation with low driving voltage. Its low insertion loss ensures maximum transmission power. The PM-1550-300-PA modulator uses polarization-maintaining (PM) input and output fibers, making it easy to integrate with other optical components.

    产品特点Bandwidth up to 300 MHz 、Operating range: 1525 nm to 1565 nm 、Low insertion loss, typical 3 dB 、Minimal back reflection 、Drive voltage: 4V @ 1 MHz

    产品货号D80020035

    应用领域Coherent communication 、Optical chirping 、Optical sensing 、FM spectroscopy 、Frequency shifting 、Laser linewidth broadening

    Phase Modulator Test Report

    The test optical path diagram is shown below：

    The following results were obtained on the oscilloscope:

    The output impedance of the AFG is 50Ω, generating a sine wave signal at 500kHz with an amplitude of 0–3.8V. The 3.8V should represent the half-wave voltage, but a full-wave phase shift is displayed on the oscilloscope, possibly due to an    impedance mismatch between the AFG and the product.
