    • 1403nm MEMS VCSEL Laser Diode

    Vertical-Cavity Surface-Emitting Laser (VCSEL) is a semiconductor laser based on gallium arsenide (GaAs) material, which emits light vertically from the top surface, fundamentally different from light-emitting diodes (LEDs) and laser diodes (LDs).It consists of reflective mirrors, an active layer, and a metal contact layer. The two emission mirrors are P-type and N-type distributed Bragg reflectors (DBR) respectively, and the active region is composed of quantum wells.A metal contact layer is fabricated on the outer surface of the P-type DBR to form ohmic contact, and a circular aperture is opened on the P-type DBR for laser output.This laser features a small far-field divergence angle with a narrow, circular beam, low threshold current, and high modulation frequency up to 300 kHz.Wavelength tuning can be realized by adjusting the driving current and operating temperature.The package integrates a thermoelectric cooler (TEC) and a photodetector (PD), specially designed for high-speed optical fiber applications.

    Product features：7-pin design; aspheric lens cap; integrated thermoelectric cooler (TEC) for temperature stability control;output power: 1.6 mW;single-mode operation covering the C-L band;broad spectral tuning range: > 8 nm;fast wavelength tuning: ~100 kHz

    Part Number：MP-VCS-1403-1.6-A81-SA-TEC

    Application area：Tunable Diode Laser Absorption Spectroscopy (TDLAS) Gas Measurement System | Face Recognition | LiDAR | Data Centers & Cloud Computing

    With a constant 5V voltage applied, the frequency was varied to obtain the figure above. Our modulation frequency is extremely high, allowing it to carry a greater amount of information and provide a faster response speed.

     

    Pin Definition

    1.2.png 

    The generation of VCSEL laser mainly consists of three components: the laser gain medium, the pump source, and the optical resonant cavity.The pump source excites the gain medium to achieve population inversion and generate light emission.Within the resonant cavity formed by the bottom and top mirrors, the light is amplified and oscillates, finally outputting from the top mirror.The output light is confined only to the central region without an oxide layer, forming vertical-cavity surface-emitting laser and producing a stable, continuous, high-quality laser beam with sufficient output power.
