DMP1KKM 905 nm 16-Channel Linear Pulsed VCSEL Array
DMP1KKM provides a 16-channel linear VCSEL format for pulsed transmitter designs in a 17.3 × 4.0 × 1.7 mm AlN ceramic package. At 25 °C, each channel delivers 70 W typical and 40 W minimum peak optical power with a 15 A drive current, 1.5-2 ns pulse width and 0.03% duty cycle. Peak wavelength is 905 nm typical within a range of 895-915 nm at that test point.
Key Highlights
- Plan a segmented transmitter layout around a 16-channel linear emitter arrangement.
- Size the per-channel optical path using 70 W typical and 40 W minimum peak output at 25 °C, 15 A, 1.5-2 ns and 0.03% duty cycle.
- Match the receiver optics around a 905 nm typical wavelength and 3.0 nm maximum spectral bandwidth at the stated test point.
- Fit the array into a compact transmitter using a 17.3 × 4.0 × 1.7 mm AlN ceramic package.
Overview
DMP1KKM brings a linear array of pulsed emitters to LiDAR, surveillance and machine-vision transmitter architectures. The package drawing, recommended PCB pad pattern and numbered channel circuit diagram support electrical and mechanical layout planning.
The electro-optical characteristics describe each channel at a defined pulse condition. At 25 °C, 15 A, 1.5-2 ns and 0.03% duty cycle, forward voltage is 20.5 V typical and slope efficiency is 4.9 W/A typical. Use those figures with the per-channel optical output when assessing the emitter and driver.

Applications
LiDAR transmitters
Use the linear channel arrangement as an emitter input for a pulsed LiDAR transmitter. Wavelength, per-channel output and beam divergence help define the source alongside the receiver, driver and transmitter optics.
Surveillance illumination
The 895-915 nm peak-wavelength range and 3.0 nm maximum spectral bandwidth provide inputs for a pulsed near-infrared illumination design. Match the emitter spectrum and coverage to the receiving equipment.
Machine-vision illumination
The linear format supports layout planning for spatially segmented illumination. Select the channel drive pattern, optics and acquisition timing around the scene your vision system needs to observe.
