HFE408X-321
The HFE408x-321 is a high-performance 850 nm VCSEL (Vertical Cavity Surface-
Emitting Laser) packaged for high-speed data communications. This product
combines all the performance advantages of the VCSEL with a custom
designed power monitor diode. The power monitor diode can be used with
appropriate feedback control circuitry to set a maximum power level for each
VCSEL. In addition, built-in power attenuation reduces the effective slope
efficiency. These combined features simplify design for high data rate
communication and eye safety.
The HFE408x-321 is a high radiance VCSEL designed to convert electrical
current into optical power that can be used in fiber optic communications and
other applications. As the current varies above threshold, the light intensity
increases proportionally.
The HFE408x-321 is designed to be used with inexpensive silicon or gallium
arsenide detectors (see HFD3081-103, HFD3081-108), but excellent perfor-
mance can also be achieved with some indium gallium arsenide detectors.
The low drive current requirement makes direct drive from PECL (Positive
Emitter Coupled Logic) or EML (Emitter Coupled Logic) gates possible and
eases driver design.
The HFE408x-321 is designed to interface with 50/125 and 62.5/125 µm multi-
mode fiber. They product circularly symmetric, non-astigmatic, narrow divergence
beams that, with appropriate lensing, fiber couple all of the emitter power.
