A vertical-cavity surface-emitting laser (VCSEL) is a semiconductor-based laser diode that emits a highly efficient optical beam vertically from its top surface. VCSEL laser diodes differ from other common semiconductor optical sources such as Edge Emitting Lasers (EEL) that emit light from the side.
Brandnew's VCSEL chips are produced in a fully independent production line in the IDM mode. Compared with other traditional VCSEL chips, they have better optical uniformity and light efficiency, no central dark spots in the light field, and a PCE as high as 44%. Mainly used in automotive night vision systems, DMS (driver fatigue monitoring), OMS (passenger monitoring), in-car gesture recognition and other scenarios.
The advantages of Brandnew VCSEL Laser Diode:
High Coupling Efficiency: The larger output aperture of VCSEL laser diode, compared to most edge-emitting lasers, produces a lower divergence angle of the output beam, and makes possible high coupling efficiency with optical fibers.
Low power consumption: The small active region, reduces the threshold current of VCSEL laser diode, resulting in low power consumption. The low threshold current also permits high intrinsic modulation bandwidths in VCSEL laser diode.
Small Footprint: VCSEL laser diodes are space-efficient laser sources. A single-emitter of a VCSEL laser diode can be as small as a few micrometers (microns) wide and tens of microns tall, leading to practical die sizes (with pads, keep out areas etc) less than 100 micrometers in all dimensions. Adding emitters to a die for more output power is as simple as laying them out side-by-side at a certain spacing or pitch.
Optimized beam profile: The round beam, which can even be Gaussian in shape, the low beam divergence and the different light modes (multimode and single-mode) make VCSEL laser diode perfect for a variety of applications.
The module product size of high-power VCSEL is 2.5*3.2*1.72mm, and a variety of angle options are available: 40*30, 50*35, 60*45, 72*58, 90*70, 110* 45, 100*90, 120*90, and can also provide customers with optical customization, including but not limited to FOV and uniformity requirements.
