    DFB Laser diode
    In the optical fiber communication network, the most commonly used laser is the distributed feedback (DFB) laser, which is a single longitudinal mode or single frequency semiconductor laser. The single frequency laser refers to a laser with only one longitudinal mode (spectral line) spectrum characteristic of the semiconductor laser. It can work in the third generation optical ...

    Exploration of Near Infrared Imaging Window
    Fluorescence imaging has been widely used in biomedical imaging and clinical intraoperative navigation. When fluorescence propagates in biological media, absorption attenuation and scattering disturbance will cause fluorescence energy loss and signal-to-noise ratio decrease, respectively. Generally speaking, the degree of absorption loss determines whether we can "see", and the...

    How does the fiber amplifier work?
    When the transmission interval is too long (more than 100 km), the optical signal will have a great loss. In the past, people generally used optical repeaters to expand the optical signal. This kind of equipment has certain limitations in practical use, and it has been gradually Instead of optical fiber amplifiers, the working principle of optical fiber amplifiers is shown in t...
