TO-46 PACKAGE

HFE409X-342

These products are high-performance 850nm VCSELs (Vertical Cavity Surface-

Emitting Lasers) designed for high-speed data communications and packaged

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 the VCSEL. These combined features simplify design for high data rate

communication and eye safety.

These products are high radiance VCSELs 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.

These products are designed to be used with inexpensive silicon or gallium

arsenide detectors, but excellent performance can also be achieved with some

indium gallium arsenide detectors (see HFD3081-002 and HFD3081-102

product data sheets).

The low drive current requirement makes direct drive from PECL (Positive

Emitter Coupled Logic) or ECL (Emitter Coupled Logic) gates possible and eases

driver design.

These are designed to interface with 50/125 and 62.5/125µm multi-mode fiber.

They produce circularly symmetric, non-astigmatic, narrow divergence beams

that, with appropriate lensing, fiber couple all of the emitter power

(see SC, LC and MU connectorized product data sheets).
