首页 Semiconductor Diodes VCSEL Laser Diode 1600-1700nm VCSEL laser diode Testing CH4 with 1654nm tail fiber VCSEL laser 1654nm pigtailed VCSEL laser test CH4

    • 1654nm pigtailed VCSEL laser test CH4

    Idealphotonics' new 1654nm VCSEL laser uses the newly invented high contrast grating layer (HCG). HCG is about 50 times thinner than the traditional distributed Bragg reflector (DBR), but has higher reflectivity and wider spectral width. Our laser has a tuning range of up to 8nm and a tuning frequency of up to 100kHz, making it an ideal choice for testing CH4 gas.

    产品特点TO-56 package, 7Pin、 Single-mode fiber, FC/APC connector、 With TEC, temperature stable、 CW continuous output power、 Single-mode VCSEL (~1654nm) fast wavelength tuning、 Built-in optical isolator, isolation ratio>20dB

    产品货号A80040024

    应用领域Optical gas sensing (CH4)、 Ranging、 Optical time domain reflectometer、 Optical communication system (U band)
